More and more people choose heat pump water heatersbecause air energy is the most energy-efficient, that is, the lowest operating cost, compared to most water heaters that consume electricity and gas.
How does the heat pump water heater achieve the effect of saving energy?
What should we pay attention to when using heat pump water heater?
What are the operational advantages of heat pump water heaters?
When the heat pump water heater is working, the energy QA stored in the ambient medium is absorbed in the evaporator; it consumes a part of the energy itself, that is, the compressor consumes power QB; the heat release QC is carried out in the condenser through the working fluid circulation system, QC=QA+QB, it can be seen that the energy output by the heat pump is the work QB done by the compressor and the heat QA absorbed by the heat pump from the environment; therefore, the use of heat pump technology can save a lot of electric energy.
temperature, water consumption
Put the bath water in the heat pump water heater. The most suitable water temperature is 42°C. It can be slightly higher by 1-2°C for middle-aged and elderly people. The water for showering is about 40~50 liters per person. Bathtubs and Jacuzzis are determined by capacity.
How much hot water can be made
In terms of product performance and theory, the heat pump water heater can be cycled back and forth to continuously produce hot water. Under normal temperature, the hot water can be produced per hour as follows (45℃-55℃): It depends on the size of the unit.
The heat pump water heater absorbs the low-temperature heat in the air, vaporizes it through the fluorine medium, and then compresses it through the compressor to heat up and pressurize it. The air energy water heater has the characteristics of high efficiency and energy saving. The same amount of hot water produced is 4-6 times that of the electric water heater. Its annual average thermal efficiency ratio is 4 times that of the electric heating, and the energy efficiency is high.
The heat pump water heater overcomes the shortcomings of solar water heaters that rely on sunlight for heating and inconvenient installation. Since the work of the air energy water heater is to exchange heat through the medium, it does not need the electric heating element to be in direct contact with the water, which avoids the danger of electric water heater leakage, and also prevents the gas water heater from the danger of explosion and poisoning, and more effectively controls the gas Air Pollution Caused by Exhaust Gases from Water Heaters.
Guangdong JNOD New Energy Technology Co., LTD. has focused on the field of heat pump water heaters for many years, it commits to providing perfect service for every customer in the world.
Winter has arrived, and people tend to use heat pumps as heating machines. If the heat pump unit can be installed reasonably, the service life and heating capacity of the heat pump will be improved. Let Jnod tell you how to install it, see below:
1. Unit installation location planning
1) The installation requirements of the heat pump main unit are similar to the installation requirements of the outdoor unit of the air conditioner. It can be installed on the roof, balcony, and ground. The air outlet should avoid the windward direction.
2) The distance between the main unit (wind from the side) and the surrounding walls or other obstructions should not be too small. There should be no obstructions within 1 meter of the air outlet, and ensure that the heat exhaustion and suction of the heat exchanger are not hindered.
3) There should be no obstructions within 1 meter of the air inlet of the main unit (top air outlet), and no obstructions within 2 meters of the air outlet to ensure that the heat exhaustion and suction of the heat exchanger of the main unit are not hindered.
When the unit is installed under the eaves or there are horizontal obstacles above the unit, the installation location of the unit must be in a well-ventilated place, otherwise it is easy to short-circuit the air flow, resulting in poor heat dissipation capacity of the unit.
2. Unit installation environment control
1) Try not to place it in direct sunlight.
2) Not on the window sill of the bedroom or near the bedroom.
3) There is enough distance between the air inlet and outlet to facilitate heat dissipation.
4) Places that can withstand more than 2-3 times the weight of the outdoor unit.
5) A place where there is no oily smoke or other corrosive gas.
6) A place that does not affect other factors or the environment.
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.

heating and cooling heat pump integrates air conditioning and heating systems, is comfortable and energy-saving, and will surely lead the market trend of comfortable home life in the future.
How exactly does the heating and cooling heat pump work?
What is the basic principle of heating and cooling heat pump?
Will the floor height affect the installation of the heating and cooling heat pump?
The common heating and cooling heat pumps on the market are almost all of combined cooling and heating, which solves the problems of cooling in summer and heating in winter through a set of equipment. In some specific areas (the temperature is relatively high in winter), the air energy heat pump can also be connected to the domestic hot water tank to provide 24-hour uninterrupted hot water for the family, so the air energy heat pump can be used for cooling and heating, as well as cooling and heating. And with domestic hot water, but in order not to affect the heating effect, the domestic hot water is generally not combined.
Basic principle of heating and cooling heat pump: it is mainly composed of compressor, heat exchanger, axial fan, thermal insulation water tank, water pump, liquid storage tank, filter, electronic expansion valve and electronic automatic controller. After the power is turned on, the axial flow fan starts to operate. The outdoor air is heat exchanged through the evaporator. The air with reduced temperature is discharged from the system by the fan. At the same time, the working medium inside the evaporator is sucked into the compressor. The compressor compresses the low-pressure working medium gas into high-temperature and high-pressure gas and sends it to the condenser. The water forcibly circulated by the water pump also passes through the condenser and is heated by the working medium and sent to the user for use, The working medium is cooled into liquid, which flows into the evaporator again after throttling and cooling by the expansion valve. In this way, the heat energy in the air is continuously "pumped" into the water, so that the water temperature in the insulation water tank gradually rises to about 55 ℃, which is just suitable for people to take a bath. This is the basic working principle of heating and cooling heat pump.
The floor height problem, many people think that the floor height of the elevator apartment is relatively low, and the installation of heating and cooling heat pump will cause the room to become depressed, but in fact, the installation of heating and cooling heat pump will not have much impact on the floor height. , The concealment of central air-conditioning can reduce the sense of oppression of the floor height through the reasonable planning of the ceiling, and the floor heating can also be laid by dry floor heating. The floor height is only increased by 3-4 cm, and the user cannot distinguish it with the naked eye.

Heating and Cooling Heat Pump is a central air-conditioning unit that uses air as a cooling (heat) source and water as a circulating medium to transfer energy. Its advantages are that it is easy to install and use, and it can be used after connecting to the power supply, saving a complex cooling water system and a boiler heating system.
Compared with other products of the same type, why is Heating and Cooling Heat Pump cost-effective?
What are the common Heating and Cooling Heat Pumps on the market?
What to look for when choosing a Heating and Cooling Heat Pump?
Compared with electric boilers, Heating and Cooling Heat Pump can save more than 50% of power consumption, and reduce the trouble of frequent replacement of electric heating tubes; Compared with traditional coal boilers and oil-fired boilers, Heating and Cooling Heat Pump is pollution-free, emission-free, and safe , eliminating the need for annual routine security inspections, eliminating the need for professional boiler workers, fully automatic temperature control, and significantly reducing operating costs by more than 50%. Heating and Cooling Heat Pump completes a heat pump for heating and cooling needs in a particular field. Generally speaking, Heating and Cooling Heat Pump uses specialized heat pump compressors, special refrigerants and systems.
There are many types of heat pump water heaters on the market, mainly including three series of solar boost type, water source and air source. Solar-assisted heat pump is a heat pump technology that combines heat pump and solar energy technology; water source heat pump uses a certain temperature water source (above 20 ℃) as a heat source and uses refrigerant as a medium to absorb the heat in the water source and then compress it by a compressor. For heating, exchange heat with cold water through a heat exchanger to achieve the purpose of heating and producing hot water. The water source heat pump must have a water source with a certain temperature and flow; the air source heat pump obtains heat from the air in a similar way to the water source heat pump to heat water. Among the three types of heat pumps, the air source heat pump is subject to the least restriction and has the largest development space.
Whether the Heating and Cooling Heat Pump saves electricity has a lot to do with outdoor temperature, building insulation, user usage, equipment purchase and installation. If you want to save more electricity, users not only need to carefully select air source products, such as buying big brands as much as possible, finding professionally qualified installers for installation, etc., but also mastering the correct air source heat pump heating method, in order to achieve high efficiency and energy saving.
