The Heating and Cooling Heat Pump is driven by an electric motor, uses the heat in the air as a low-temperature heat source, exchanges heat through the air conditioner condenser or evaporator, and then passes through the circulation system to extract or release heat energy, and use the unit circulation system to transfer the energy to the building. It can meet the needs of users for domestic hot water, floor heating or air conditioning.
What is the cycle between the Heating and Cooling Heat Pump and the natural environment?
What is the principle of Heating and Cooling Heat Pump?
Does the Heating and Cooling Heat Pump make noise?
The compressor outlet of the Heating and Cooling Heat Pump is high-temperature and high-pressure gas, which is transformed into a high-pressure and low-temperature vapor-liquid mixture through the heat exchange of the condenser. The low-temperature gas enters the evaporator to evaporate and absorb heat, and absorb the low-grade heat energy from the outside world (which can be rivers, lakes, groundwater, underground soil layers, air, etc., which we call water source, ground source, and air source heat pump), and finally the evaporator comes out. The low pressure gas enters the compressor to complete the cycle.
Heating and Cooling Heat Pump is an evolved product of air conditioners. An electromagnetic four-way valve (also known as a reversing valve) is installed in the refrigeration system. Through the switching direction of the four-way valve, the flow direction of the refrigerant is changed, and the air conditioner can hot. The high-temperature and high-pressure vapor-like refrigerant discharged from the compressor flows to the condenser in the heat preservation water tank, transfers heat to the tap water passing through the water tank, and then throttles and reduces the pressure through the expansion valve, and evaporates and absorbs heat in the evaporator of the main outdoor heat pump group. Use the working fluid to absorb the heat in the outdoor air. The Heating and Cooling Heat Pump absorbs the heat in the outdoor air and transfers it to the tap water in the insulated water tank. It is more energy-saving, fast and safe than simply heating with an electric heater, and the outdoor thermal energy potential is infinite.
Noise problem, almost all of today's Heating and Cooling Heat Pumps use full frequency conversion technology, indoor unit frequency conversion, heat pump host frequency conversion, fan frequency conversion, etc. The noise value of the heat pump host is below 45 decibels, and the indoor noise is still below 20 decibels. Neither users nor neighbors will be affected.
JNOD has a complete heat pump industry chain, and its products involve Swimming Pool Heat Pump, House Heating & Cooling Heat Pump, Domestic Hot Water Heat Pump, Heat Pump Dehumidifier, Commercial & Industrial High Temperature Water Heating Solution, Industrial and Agricultural Heat Pump Dryer, etc. The ultra-low temperature EVI heat pump has been widely used, too.
In fact, the working principle of the Heat Pump Hot Water Heater does not differ significantly from the working principle of our air conditioning system. However, our household air conditioners use the cold end (evaporator) of the cooling circuit system; In contrast, heat pumps use the hot end (condenser) of the circulatory system.

The basic principle of heat pump water heater: It mainly consists of compressor, heat exchanger, axial fan, heat storage water tank, water pump, liquid storage, filter, electronic expansion valve and electronic automatic control. After switching on the power supply, the axial fan starts running, the outside air flows through the evaporator for heat exchange, and the reduced temperature air is expelled from the system by the fan. A kind of low pressure working medium gas is compressed into high temperature and high pressure gas and fed to the capacitor. The water forcibly circulated by the water pump also passes through the condenser and is heated by the working medium and fed to the consumer for use. The working medium is cooled to a liquid and the liquid expands. After the valve is throttled and cooled, it flows back into the evaporator. This cycle works repeatedly, and the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the water tank for heat preservation gradually rises and finally reaches about 55°C, which is just suitable for people to take a bath.
Heat pump water heaters are a new thing on the market, and consumer awareness of this is still very low. There are many people who think that it is impossible to get three parts heat with one part heat, and the same applies to other products related to the application of heat recovery technology, although the popularity of heat pump air conditioners was very high.
People's understanding is limited only to the fact that air conditioning is a large electricity consumer, but they do not know that it is more energy-saving than the coal-fired ball furnace. As some larger shopping malls have not yet sold air-powered water heaters, consumer awareness of air-powered water heaters is still very low.
In order to meet these growing requirements, Guangdong JNOD New Energy Technology Co., LTD. has various heat pump water heaters, which allow to increase the products and make them more effective, reliable and consistent.
Heat pump water heater is a new type of water heater. It converts air energy into heat energy through a heat pump to produce hot water. This water heater solves the disadvantage that solar energy cannot be used on rainy days. In addition, this water heater is more efficient compared to gas water heaters and electric water heaters. Environmental protection when you choose this water heater is a very good choice.
What is the main reason why air heat pump water heaters are popular in the market?
What is the workflow of a heat pump water heater?
What do you know about heat pump water heaters that can be used in hotels?
Air Source Water Heater is a new type of low carbon and environmentally friendly water heater. The operating cost of heat pump water heaters is only 1/4 of the cost of electric water heaters, which is very energy-saving and efficient. Originally, as a fourth-generation air water heater, its greatest feature is safety and money-saving! The operating costs of the air water heater are only 1/4 of the electric water heater, 1/6 of the gas water heater, 1/2 of the solar water heater, 2/3 of the fuel water heater and 3/5 of the gas heating system. The device absorbs the heat in the air to heat the cold water, and the cool air released does not pollute the environment and completely eliminates the safety risks such as flammability, explosion, electric shock and gas poisoning of ordinary water heaters.
1. The compressor compresses the low pressure refrigerant flowing back and converts it into a gas with high temperature and high pressure for discharge.
2. The high temperature and high pressure refrigerant gas flows through the copper pipe wrapped around the outside of the water tank, and the heat is passed through the copper pipe into the water tank. The cooled refrigerant becomes liquid under constant pressure and enters the evaporator after passing the expansion valve.
3. As the pressure of the evaporator is suddenly reduced, the liquid refrigerant is quickly evaporated into a gaseous state and absorbs a large amount of heat.
4. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, the energy in the air is absorbed by the evaporator, the air temperature drops quickly, and cold air is released and released.
5. The refrigerant that has absorbed a certain amount of energy is then returned to the compressor and enters the next circuit.

JNOD has a complete heat pump industry chain, and its products involves Swimming Pool Heat Pump, House Heating & Cooling Heat Pump, Domestic Hot Water Heat Pump, Heat Pump Dehumidifier, Commercial & Industrial High Temperature Water Heating Solution, Industrial and Agricultural Heat Pump Dryer,etc.The ultra-low temperature EVI heat pump has been widely used, too.
Heating and cooling heat pump is a device that transfers thermal energy from a low temperature heat source to a high temperature heat source. for cooling and heating. The low-temperature heat sources usually used in heat pump installations are the media around us - air, river water, sea water, urban sewage, surface water, groundwater, reclaimed water, fire pools, or the working fluid discharged from industrial production equipment, these working fluids Often has a similar temperature to the surrounding medium.
How does the heating and cooling heat pump work?
Compared with ordinary central air conditioning refrigeration and gas wall-hung boiler heating, why does heating and cooling heat pump feel better?
What are the installation precautions for heating and cooling heat pump?
Water flows from high to low, and heat is transferred from high-temperature objects to low-temperature objects, which is a natural law. However, in real life, for the needs of agricultural irrigation, domestic water, etc., people use water pumps to send water from low places to high places. Similarly, in today's increasingly tense energy environment, in order to recover the heat in the low-temperature hot gas usually discharged into the atmosphere, the low-temperature hot water discharged into the river, etc., the heating and cooling heat pump is used to transfer the heat energy from the low-temperature objects to the high-temperature objects. Then the high temperature object is used to heat water or heating, so that the heat can be fully utilized. The working principle of the heat pump system is consistent with the working principle of the refrigeration system.
Heating and cooling heat pump has an additional heat exchange procedure in the cycle process, and the temperature difference of the system heat exchange is smaller (the air temperature of the fan coil unit in summer is 15℃-20℃, and the air temperature of the fan coil unit in winter is about 32℃) , the wind blowing out is softer, it will not take too much moisture, and the comfort is much better.
The installation location of the heating and cooling heat pump is a problem. Many people look at the installation example and think that the heat pump host with a water tank takes up too much space. The installation of the elevator apartment has to occupy a large living balcony or kitchen space. In fact, the air energy heat pump is also related to the power Related, the equipment of a large apartment is very large, and the equipment of a small apartment will be very small, and it can even be installed on an ordinary central air-conditioning unit.
Guangdong JNOD New Energy Technology Co., LTD. can provide product certification requirements for local markets; provide catalogs, technical manuals; co-exhibit with the clients in leading industry exhibitions; do promotion on the local market's media by our news release resources.
The operating principle of heat pump water heaters is very similar to that of air conditioning systems. It consumes a small amount of electrical energy to get the compressor running. The working fluid is compressed by the compressor into a liquid state with high temperature and high pressure, and then enters the condenser to release heat to heat the water. By circulating and heating in this way, the water can be heated from 50°C to 65°C.
What are the main components of heat pump water heaters?
How does the heat pump water heater work?
Why should the heat pump water heater be green?
Four main components of refrigeration technology: evaporator, compressor, condenser and throttling device.
Three stable parts: liquid storage tank (compressor), expansion valve (capillary tube), dry filter (filtering water and impurities)
A large piece of defrosting: four-way valve
Break through traditional energy conversion theory to achieve high energy efficiency:
When operating the heat pump, the working medium in the evaporator can absorb the energy QA stored in the ambient medium;
And starting the system must consume energy, that is, the power consumption of the QB compressor;
At the same time, the heat emitted from the working medium to the high temperature medium in the condenser is QC;
After the compressor input work starts the system, the mechanical kinetic energy becomes thermal energy. The energy output of the heat pump is thus the sum of the work done by the compressor QB and the heat absorbed by the heat pump from the environment QA; Enter a QB to get QB+QA and break the traditional bottleneck that conversion between different energies cannot achieve full efficiency; Heat pump technology is more energy efficient.
heat pump water heaters work according to the "reverse carnotic" principle, specifically the "outdoor unit" as a heat exchanger absorbs heat from the outside air, heats the low boiling working medium (refrigerant) and evaporates it, and the refrigerant vapor The water is compressed and heated by the compressor and enters the water tank, and the water in which the heat is released is condensed and liquefied and then throttled and pressurized to return to the outer heat exchanger to enter the next circuit. The heat pump water heater simply absorbs the heat in the air to heat the water, and the air that has absorbed the heat can also be used in the kitchen to solve the problem of stuffy heat.
The heat pump water heater has energy saving functions.
The biggest advantage of the heat pump water heater is undoubtedly the energy saving. The low-temperature thermal energy in the air is converted into high-temperature thermal energy by the compressor. Based on the same amount of hot water generation, the energy saving is maximized compared to the water heater with electric heating, and the cost of use is only 1/4 of the cost of electric water heater. Compared to gas water heaters, it consumes no gas fuel and the cost of use is only 1/3 of the cost of gas water heaters. heat pump water heaters take air as the main body and save energy, which not only saves people's usage cost, but also corresponds to the main body of energy saving in the world. This is one of the biggest highlights of air energy water heaters.
Guangdong JNOD New Energy Technology Co., LTD. Focus on research and development of heat pumps and electric boilers, manufacturing and providing comprehensive energy saving solutions.
Heating and Cooling Heat Pump installs a four-way reversing valve on the basis of ordinary air conditioners, and changes the operation of the valve, which can exchange the functions of the evaporator and the condenser of the original air conditioner, so as to change the function of cooling indoor air. Changed to the function of heating indoor air.
What are the structural advantages of the Heating and Cooling Heat Pump?
What is the user's experience with Heating and Cooling Heat Pump?
Why the use of Heating and Cooling Heat Pump can save resources?
The evaporator of the Heating and Cooling Heat Pump adopts the method of countercurrent heat exchange for heat exchange to enhance the heat exchange effect; moreover, the heat exchange method combining fins and tube bundles is used, and each row of heat exchange tubes is arranged in a cross. The method of turbulence increases the convective heat transfer coefficient on the exhaust side and enhances the heat transfer effect;
The refrigerant tube bundle of Heating and Cooling Heat Pump is made of red copper, and the fins are made of hydrophilic aluminum foil. The condensed water in the exhausted air drips on the surface of the heat exchanger to form a water film that is conducive to heat exchange, increasing the heat exchange coefficient and enhancing the heat exchange effect;
The Heating and Cooling Heat Pump has an advanced microcomputer control system, and adopts a special programmable controller PLC for imported air-conditioning equipment, which has the ability to resist electromagnetic interference, intelligent coupling between building load and unit heating; Display, fault alarm and diagnosis functions.
The Heating and Cooling Heat Pumpis also very comfortable, clean and safe. In the past, when burning coal, it was not only dirty, tiring and troublesome, but also the temperature was not high, usually 14-16 degrees, and you had to wear cotton-padded clothes at home. Now open to 18 degrees and wear a thin sweater. If the weather is cold, turn up the temperature. Anyway, the Heating and Cooling Heat Pump is also very convenient, and you can adjust the temperature by pressing a button.
The Heating and Cooling Heat Pump unit has the dual functions of supplying cold water in summer and supplying hot water in winter. Using air as the heat source and cooling source can greatly save water and avoid the pollution of water quality. The air-cooled modular cold and hot water unit can be placed on the top floor of the building or on the outdoor platform to work, eliminating the need for a dedicated cold source machine room and boiler room.
