The working principle of the Heating and Cooling Heat Pump is a mechanical device that forces heat to flow from a low temperature object to a high temperature object in a reverse cycle. The applied low-grade thermal energy is utilized to achieve the purpose of energy saving.
How does the Heating and Cooling Heat Pump perform cooling and heating respectively?
What is the principle of Heating and Cooling Heat Pump?
Why is Heating and Cooling Heat Pump so practical?
When the air conditioner cools down in summer, the Heating and Cooling Heat Pump operates according to the cooling condition, and the high-pressure steam discharged from the compressor enters the condenser through the reversing valve (also known as the four-way valve); when heating in winter, the reversing valve Turn to the working position of the heat pump, so the high-pressure refrigerant vapor discharged from the compressor flows into the indoor evaporator (used as a condenser) after passing through the reversing valve, and the latent heat released when the refrigerant vapor condenses heats the indoor air to achieve indoor heating purposes. The condensed liquid refrigerant flows in the reverse direction through the throttling device into the condenser (used as an evaporator), absorbs external heat and evaporates, and the evaporated steam is sucked by the compressor after passing through the reversing valve to complete the heating cycle. In this way, the Heating and Cooling Heat Pump "pumps" the heat from the outside air (or circulating water) into the room with a higher temperature, so it is called a "heat pump"
When the air conditioner cools down in summer, it operates according to the refrigeration condition. The high-pressure steam discharged from the compressor by the Heating and Cooling Heat Pump enters the condenser through the reversing valve (also known as the four-way valve), and the refrigerant vapor is condensed into liquid. The flow device enters the evaporator, absorbs heat in the evaporator, cools the indoor air, and the evaporated refrigerant vapor is sucked by the compressor after passing through the reversing valve, and this cycle is repeated to realize the refrigeration cycle.
Heating and Cooling Heat Pump can operate normally between -27℃-48℃, and some low-temperature air-energy heat pumps are also capable of -35℃ ambient temperature, and still maintain normal operation. In our environment, a It can be used all-weather all year round, and will not be affected too much by rainy, windy and snowy weather, nor will it be affected by low temperature at night. However, solar heating equipment is greatly affected by environmental factors. In the case of insufficient light, it is difficult to achieve the effect of indoor heating, especially in areas with low ambient temperature in winter.

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.

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.

JNOD are selling R32 inverter swimming pool heat pump, its heating capacity ranges from 5.5-32Kw. So, it will be a problem for user or wholesaler to choose the suitable heating capacity for different pool sizes. Let us show you 2 methods to choose the suitable.
If you do not want to do complicated calculations and do not take into account extreme weather, you can use the following formula: 3KW for 10m³. For example, if you want to heat a 30CBM pool, (30 CBM÷10CBM)* 3KW = 9KW . So, you can choose the 9.5Kw model.
This method is used to do a very precise calculation on the heating capacity, considering the heating time, water temperature, ambient temperature, etc.
* Step 1: Calculate the needed heating capacity
In the calculation, we usually set the outlet water temperature at 28℃, primary heating time usually is 48hours.
Formula will use: Q=1.163*△t*V ;
W=Q/T
Explanation: Q = Heat Demand (KwH)
△t = Temperature Difference (℃)
V = volume of pool (m³)
W = Heat pump capacity(Kw) - usually will add 15-25% of heat loss
T = Hours for heating (H)
Example: A swimming pool 10*4*1.5m, original temperature is 18℃
Answer: set the target temperature into 28℃, heating hour into 48 hours
Q = 1.163*(28-18)*(10*4*1.5)=697.8 KwH
W= (1+15%) *Q/T=1.15*697.8/48=16.72 KW
*Step 2 : Choose the suitable heating capacity depending on working condition
The heating capacity of a heat pump is not constant; it changes with the ambient temperature. Therefore, after calculating the required heating capacity, we also need to choose the model we need according to the ambient temperature.
Still that sample, we calculate that 16.72Kw is needed. If the ambient temperature is around 24-27℃, you can choose the 17.5Kw model; if ambient temp is around 12-15℃, better to choose 25kw model.
Model | J175P32INVP | J210SP32INVP | J250SP32INVP |
Ambient Temperature:(DB/WB)27℃/24.3℃ | |||
Heating Capacity (kW) | 4.34~18.1 | 4.72~21.21 | 5.05~25.28 |

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.
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.
