More and more northern == home users and schools, hotels, hospitals When transforming the original heating system in other places, choose to use Heating and Cooling Heat Pump.
Compared with ordinary central air conditioning refrigeration and gas wall-hung boiler heating, what are the advantages of Heating and Cooling Heat Pump?
What are the advantages of using the Heating and Cooling Heat Pump?
What is the working principle of Heating and Cooling Heat Pump?
The common heating and cooling equipment on the market is mainly fluorine system heating and cooling air conditioning or the combination of gas wall-hung boiler heating and central air conditioning refrigeration.
The main advantage of Heating and Cooling Heat Pump compared to ordinary heating and cooling air conditioners is high comfort. The fluorine system heating and cooling air conditioner directly controls the indoor temperature through the flow of the refrigerant, and the refrigerant directly exchanges heat with the air. This heat exchange method has two disadvantages: First, the temperature of the air outlet of the air conditioner is very low or very high (7°C-12°C during cooling, 40°C-50°C during heating), the body feels very bad, and it is bitingly cold in summer. The winter is hot and dry; second, although the fluorine system air conditioner has a relatively fast cooling and heating speed, it will also cause a large amount of moisture in the air to be taken away due to the rapid heating and cooling speed, resulting in excessive indoor dehumidification and drying.
1) The unit of Heating and Cooling Heat Pump has high energy efficiency ratio, energy saving and electricity saving.
2) The water temperature of the Heating and Cooling Heat Pump is generally constant at 12-22°C, which is 7°C for the water supply in summer, 12°C for the return water, 45°C for the water supply in winter, and 40°C for the return water, and the temperature difference between them is small. , so the unit has less work and more energy.
During the operation of Heating and Cooling Heat Pump, the evaporator absorbs heat from the ambient heat energy in the air to evaporate the heat transfer working medium. After the working medium vapor is compressed by the compressor, the pressure and temperature rise. When the high-temperature vapor passes through the special annular pipe bonded on the outer surface of the water storage tank, the condenser condenses into liquid and transfers the heat to the water in the water storage tank of air source heat pump.
Guangdong JNOD New Energy Technology Co., LTD. has focused on the development and production of Heating and Cooling Heat Pumps for several years. And it commits to providing perfect service for every customer from all over the world.
The heating and cooling heat pump is a device that transfers heat energy from a low-level heat source to a high-level heat source, and is also a new energy technology that has attracted a lot of attention worldwide. It differs from the well-known mechanical equipment, which can increase the potential energy"Pumps"; A heat pump usually first extracts inferior heat energy from natural air, water or earth, then performs work by electricity, and then provides people with available energy that can be used. of high quality thermal energy.
What is the working medium of the heating and cooling heat pump?
What role does the heating and cooling heat pump play?
What do you know about heating and cooling heat pumps?
The working medium of the heating and cooling heat pump used to be Freon, but since Freon adversely affects the Earth's atmospheric ozone to protect the Earth's ecological environment, in addition to improving the cooling coefficient of the heat pump and effective use, science is also committed to new technologies in various countries. With the development of quality, the working fluid was used as a replacement for Freon. However, the work equipment of most Chinese manufacturers today is still R22, and the era of using environmentally friendly work equipment R417A and 134A has not yet arrived. Some countries, such as Japan, have taken the lead in using CO2 as a working medium to avoid damaging the ozone layer. (Therefore, the copper pipes must be firmly connected during installation to prevent R22 from leaking.) In addition, the above R22, R417A, 134A and CO2 do not harm the human body. Even if there is a leak, all the equipment is still safe.
The low temperature heat sources normally used in heat pumps for heating and cooling are the media around us. Air, river water, seawater, municipal wastewater, surface water, groundwater, treated water, fire pits or working fluids, which are discharged from industrial production plants these working fluids often have similar temperatures to the surrounding medium. The operating principle of the heating and cooling heat pump is the same as that of the compression chiller. In order to fully exploit its efficiency, the small air conditioner is cooled with the same equipment in summer or heated in winter. When heating in winter, the evaporator and condenser in the air conditioning system are exchanged via a switching valve.
Heat pumps for heating and cooling are an intelligent, efficient and versatile solution for year-round heating, cooling and hot water supply solutions. In addition to their flexibility and wide application, they are energy efficient and environmentally friendly, with advanced EVI technology and green refrigerant R32/R410A. So you can enjoy a comfortable home and save energy at the same time.
JNOD insisted on developing with technological innovation, it had several nationally famous technicians and had invented several product patents. The company has strictly implemented the international ISO quality management system, and the products are of reliable guaranteed quality.
The heat pump water heater uses a heat pump to absorb the air heat source to produce hot water. The energy saving efficiency is more than 3 times that of the electric water heater. It is more energy efficient than the solar water heater.
What is a direct heat pump water heater?
What are the characteristics of direct heat pump water heaters?
What is the main structure of the direct heat pump water heater?
The direct heat pump water heater is also known as the fast or fast heat pump water heater. The basic characteristics of the direct heat pump water heater are: cold water and superheated water, as long as the tap is turned on, the energy source will continuously supply hot water within a few seconds. Turn off the faucet when you don't need hot water.
According to different heating forms, direct heat pump electric water heaters can be divided into the following three types:
①, bare electric wire heating electric water heater;
②, electric film heating electric water heater;
③, electric heating tube heating electric water heater.
The heater of the direct heat pump water heateris set in a tank frame, which cannot withstand too high water pressure. At the same time, the left and right poles of the tank frame and the two poles introduced by the heating wire will be affected by water pressure for a long time. be damaged. Therefore, direct heating heat pump water heaters cannot be made into the post-system, but are all made into the front-system. In addition, in order to ensure the safe use of direct-heat heat pump water heaters and no dry burning occurs, a pressure sensing activation switch with water flow as a signal is installed at the cold water inlet, and the pressure sensing activation switch diaphragm can withstand the pressure. It is limited and cannot withstand pressure for a long time, so direct heat pump water heaters are generally made into the former system.
A typical direct heat pump water heater is mainly composed of a heating tank plate, a pressure sensor, a power regulator, a water volume adjustment faucet, a water inlet pipe and a water outlet pipe component, among which the heating tank plate is the key component of the direct heat pump water heater. It consists of a groove weight, a sealing ring, a cover and an electric heating element, and the electric heating element is located in the groove of the groove plate.
The direct heat pump water heater works by direct conduction heating. Since the electric heating element is placed in the groove of the groove plate, when the cold water flows through the groove, it can directly flow through the surface of the heating element to be heated. And because the water tank is like a snake, the cold water flowing into the water inlet is gradually heated, and hot water with a higher temperature can be obtained at the water outlet.
Guangdong JNOD New Energy Technology Co., LTD. can produce standard products under clients' brand, modify the products to satisfy client's personalized requirements and work together with clients to design and produce totally new products.
The inverter technology is considered a perfect solution when it comes to energy-efficiency and economical operation. In an inverter model from a heat pump inverter manufacturer, the cooling and heating are automated in an energy-efficient and seamless manner whereas earlier technologies used to consume a lot of electricity irrespective of the required usage.This will be good to cut-off your electricity bill.
The compressor motor used by DC inverter heat pump manufacturer does not turn on and off all the time but keeps working at low power. This kind of machine makes the operation more quite.
Unlike non-inverters, they don't automatically turn on and off every time they reach a certain temperature; instead, they just cruise along maintaining and regulating the temperature constantly.
The technology and hardware employed in DC inverter model by DC inverter heat pump supplier not only makes the cooling and heating effect more efficient, but also makes the unit last longer. Contrary to the operation of a non-inverter unit, the inverter uses less power and as a result, they work less, meaning that they are less prone to wear and tear.
The DC inverter heat pump is able to cool and heat your room faster than its non-inverter counterpart. This is due to the fact that an inverter heat pump unit operates on a variable speed compressor rather than at a fixed speed one. This process ensures rapid air conditioning effects via faster variable speed allowing the compressor to run at full power only when required while constantly regulating the temperature as per end user's desire.
A smart DC Inverter heat pump will provide you complete control over energy consumption and usage through your PC and portable smart devices. Moreover, it will give you complete insights about all technical metrics such as watts, voltages, current and units consumed. A smart heat pump also lets the user schedule the heat pump to automatically turn itself on or off. Operations of a heat pump are more flexible and centralized when it is smart.

Air source heat pump water heaters are the same as the heating principle of air conditioners, they are all heat carriers. The air conditioner moves the outdoor heat into the room, and the air energy water heater moves the outdoor heat to the water tank to heat the cold water in the water tank. Because the heat in the air is free, the air energy water heater also saves electricity.
What is the operating mode and principle of the unit composition of the heat pump water heater?
What are the benefits of installing a heat pump water heater?
What is the difference between a heat pump water heater and an air conditioner?
The heat pump hot water unit is composed of a refrigeration cycle, including two parts: the main engine and the condenser. The main engine part includes evaporator, fan, compressor and expansion valve; the condenser is an incubator with condensing coils inside. The refrigerant absorbs the heat from the outside air in the evaporator and releases heat in the condensing coil through the heat pump cycle to heat the water in the water tank. The thermal insulation layer of the water tank is foamed with closed-cell rubber sponge or polyurethane, and has good thermal insulation performance.
1. Safety: No gas, no waste gas, and no "gas poisoning"; no electric heating rod for heating, there is no danger of leakage, and people's health and safety are protected.
2. Save money: The COP value is more than 3, the energy efficiency ratio is high, and it definitely saves electricity and money. It can save 2/3~3/4 of electricity expenses, or 1/2~2/3 of gas expenses and auxiliary heating expenses of solar water heaters.
3. Comfort: automatic constant temperature and pressure water supply, never hot and cold when using hot water, hot water has pressure, good comfort. All-weather supply of domestic hot water makes up for the embarrassment of solar energy when there is no hot water available in rainy days, nights, no sunlight, and freezing.
4. Environmental protection: The cold air discharged from the heat pump water heater is beneficial to reduce the room temperature.
Comparison of heat pump water heaters and air conditioners: The principle of heat pump water heaters and air conditioners is the same, but the technical content of heat pump water heaters is higher than that of air conditioners, which is why heat pump water heaters have only been listed in recent years. In general, heat pump water heaters are the product of the development of science and technology to a certain stage. The heat dissipation temperature of the air conditioner cannot work in an environment where the cooling temperature is 40~50°C, and the water temperature of the heat pump water heater can reach about 60°C or even higher.
