The heating and cooling heat pump is a highly efficient, energy-saving device that makes full use of inferior thermal energy. Heat can be transferred spontaneously from a hot object to a cold object, but not spontaneously in the opposite direction.
How does the heating and cooling heat pump work?
What does the operating time of the heating and cooling heat pump have to do?
What is the function of the heating and cooling heat pump?
In the heating and cooling circuit of the heat pump, the heat Q0kcal/h is obtained from the low temperature heat source (outside air or circulating water whose temperature is higher than the evaporation temperature t0) and the mechanical work ALkcal/h is consumed, while the heat of Q0kcal/h is obtained from the low temperature heat source (outside air or circulating water whose temperature is higher than the evaporation temperature t0) and the mechanical work ALkcal/h is consumed. The heating system) provides the heat of Q1kcal/h, and the relationship between these heats corresponds to the first main law of thermodynamics, ie Q1=Q0+ALkcal/h
If the heating and cooling heat pump is not used and the heat is converted by mechanical work (or the high temperature heat source is heated directly by electrical energy, the heat obtained is ALkcal/h, and after the heat pump device is used, the high temperature heat source (heating system) receives more heat is obtained: Q1-AL=Q0, kcal/h This heat is obtained from a low temperature heat source, and this heat cannot be obtained without a heat pump device. Therefore, using a heat pump device can save fuel and use waste heat.
The working cycle of a heating and cooling heat pump is exactly the opposite of that of a thermal engine. A thermal engine uses the energy of a high-temperature heat source to generate mechanical work, while a heat pump transfers heat from a low-temperature heat source to a high-temperature object by consuming mechanical work.
If the heat pump and the heat engine have two identical heat source temperatures, the thermal efficiency of the heat engine cycle is η=AL/Q1; the energy index of the thermal engine cycle – the heat conversion coefficient φ=Q1/AL, i.e. φ=1/η. The value of η is always less than 1, so the value of φ is greater than 1.
If the refrigerator and the heat pump have two identical heat source temperatures, the relationship between them is φ=Q1/AL=(Q0+AL)/AL=e+1, where η is the refrigerator's cooling coefficient. It can be seen that the minimum value of the heat transfer coefficient φ η1 and in this limit case Q0 E0, that is, no heat is absorbed from the low temperature heat source.

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.

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.

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.

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.

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.
