During the working process of the heat pump water heater, it consumes 1-part electricity to get the compressor running, and at the same time, it can absorb about 4-part heat from the ambient air and transfer it to the water. Therefore, air energy water heaters can save almost 3/4 electricity compared to electric water heaters. That is, the electric water heater consumes 4 kWh electricity to produce hot water, and the air energy water heater requires only 1 kWh electricity.
What role does the refrigerant play in the unit composition of the heat pump water heater?
What is the physical principle of how a heat pump water heater works?
What is the significance of the appearance of heat pump water heaters?
The heat pump unit contains a special heat-absorbing refrigerant. In the liquefied state, the normal temperature is below minus 20°C. Therefore, there is a temperature difference between it and the outside temperature. The refrigerant absorbs the outside temperature and is stored in the evaporator. Generate pressure and evaporate and evaporate, and through the work of the heat exchanger (heat pump), when the refrigerant is transferred from the evaporated state to the liquefied state, the objectively existing heat is released to the storage water in the water tank.
The heat pump water heateruses the heat absorbing medium (refrigerant) in the device to collect heat energy from the air or the natural environment, heats the cold water quickly through the heat exchanger and at the same time releases the cold air, avoiding the lack that conventional solar products can not work in rainy weather and at night. As long as the outside temperature is above 1-15 degrees, it can work normally, so can be more efficient and energy-saving, at the same time does not occupy open space, and is easy to install and flexible to use.
With the rapid development of the economy and the improvement of people's living standards, water heating has become a necessity for people's lives. However, conventional electric water heaters have the disadvantages of large energy consumption, high cost and serious environmental pollution; while the operation of energy-saving and environmentally friendly solar water heaters is also restricted due to weather conditions. The heating principle of the air heat pump is different from that of the conventional solar water heater. The air heat pump uses air, water, solar energy, etc. as a low temperature heat source, and the air heat pump uses the electrical energy as energy to absorb heat from the low temperature side to heat the service water.

So, what is a heat pump?
A heat pump is part of a home heating and cooling system and is installed outside your home. Like an air conditioner such as central air, it can cool your home, but it’s also capable of providing heat. In cooler months, a heat pump pulls heat from the cold outdoor air and transfers it indoors, and in warmer months, it pulls heat out of indoor air to cool your home. They are powered by electricity and transfer heat using refrigerant to provide comfort all year round. Because they handle both cooling and heating, homeowners may not need to install separate systems to heat their homes. In colder climates, an electric heat strip can be added to the indoor fan coil for additional capabilities. Heat pumps do not burn fossil fuel like furnaces do, making them more environmentally friendly.
Also with water tank inside, it can provide DHW for your kitchen and bathroom.
To achieve heating for our house, there are total three kinds of heat pump we manufacture for our customer. They are:
1. Swimming pool heat pump;
2. Hot water heat pump;
3. Multi function heat pump (heating, cooling & DHW)
Homeowners in need of a new heating or cooling system, may consider the type of climate they live in before purchasing a heat pump system. Heat pumps are more common in milder climates, where the temperature does not typically drop below freezing. In colder regions, they can also be combined with EVI system for energy-efficient heating on all but the coldest days.
JNOD are using R134a, R410a, R32 & R290 on our heat pump products. We have range from 10kw to 32kw. Product type are with monoblock & split.

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.

Air heat pump water heater has low energy consumption (power consumption saves more than 2/3 compared to conventional electric water heaters), high thermal efficiency (heating speed is four times higher than conventional electric water heaters), Environmental protection and energy saving (reduces more than 2/3 compared to conventional electric water heaters) carbon dioxide emissions).
What are the differences between heat pump water heaters and air conditioners?
Why do heat pump water heaters improve the consumer experience?
What is the working process of the heat pump water heater?
The operating mode of the heat pump water heater is very different from that of the air conditioner, which determines the difference in the design concept between the heat pump compressor and the air conditioner compressor. Trouble-free, long-term stable operation of heat pump water heaters Compared to air conditioning systems, there is a big difference in the operating time. The operating time of heat pump water heater systems is much longer than that of air conditioning systems. The operating time of a heat pump water heater depends on the following factors: Air conditioning systems are often used in summer, but water heaters are mass-produced and run particularly long in winter. The time for heating a water tank in winter is several times as long as in summer, so it is necessary to confirm the operating mode of the heat pump water heater in winter.
According to statistical calculations, 2/3 of the service life of the heat pump water heater is consumed in winter. Since the water outlet temperature of the heat pump is over 55°C, the temperature of the water tank decreases when using. The liquefaction temperature is the main factor affecting the service life of the compressor. Under the condition of simultaneous operation, the total load of the compressor in the heat pump water heater is much higher than that of the compressor in the air conditioning system. The main motivation for consumers to buy water heaters with heat pump is energy saving and comfort. Consumers will thus consume more water, which also extends the working time of the heat pump. If the heat pump water heater is used for heating and service water applications, it can run for a long time during the heating period. From the combination of the above factors, it is evident that the main motor of the heat pump water heater will develop in the direction of miniaturization, and the actual operating time will be greatly extended.
A water heater with compression heat pump mainly consists of evaporator, compressor, condenser and expansion valve. Thermal Circular Process Throttling → Re-evaporation, whereby heat from the environment is transferred to the water.

In recent years, the potential energy of the sports industry under the national fitness, and favorable policies such as swimming into the high school entrance examination sports, the constant temperature swimming pool was once in short supply, and the Swimming Pool Heat Pump was out of stock.
What is the first stage of the workflow of Swimming Pool Heat Pump?
What is the second stage of the workflow of Swimming Pool Heat Pump?
What should we pay attention to when using Swimming Pool Heat Pump?
In the first step, the indoor hot and humid air in the swimming pool first exchanges heat with the outdoor fresh air through the heat exchanger to become warm and humid air, and then the warm and humid air flows through the evaporator, the temperature drops, and the water vapor condenses into cold water droplets and is separated from the air. Make the air dry and realize the function of air dehumidification; at the same time, the heat energy (latent heat and sensible heat) is released in the process of air cooling, water vapor condensation and cooling are absorbed by the refrigerant.
In the second step, the heat energy absorbed by the refrigerant first (latent heat) heats the pool water through the heat exchanger to realize the pool water heating function: the residual heat (sensible heat) passes through the air condenser to heat the cooled indoor air to realize the air insulation function. In the severely cold winter, when the energy available for the heat pump to extract in the air is too small, and the heat energy recovered by the heat pump is not enough to meet the requirements of the indoor air temperature, the auxiliary air heater is added to supplement the heat energy required for the indoor hot air. The Swimming Pool Heat Pump only needs to provide its own operating power, that is, it runs continuously according to the above working procedures, and achieves a harmonious balance of the three functions of pool water heating, air conditioning and dehumidification with low energy consumption.
1. When maintaining and cleaning the Swimming Pool Heat Pump, make sure that the Swimming Pool Heat Pump is in a power-off state. In addition, when the heat pump is not in use: the power supply should also be cut off.
2. Do not use gasoline, Tianna water, volatile oil, solvents and other chemicals, or liquid pesticides on the Swimming Pool Heat Pump, otherwise it may cause parts to crack and deform.
3. The area around the Swimming Pool Heat Pump should be kept dry and well ventilated.
4. Regularly clean the air-side heat exchanger to maintain a good heat exchange effect. If the shutdown time is long, the water in the pipeline of the unit should be drained, the power supply should be cut off, and the protective cover should be put on. When it is necessary to use it again, the system must be thoroughly checked before turning it on.

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.
