Guangdong JNOD New Energy Technology Co., LTD. has various Swimming Pool Heat Pumps that can provide the best quality, and make people feel more comfortable, reliable, and consistent.
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 |

What do you know about heat pump water heaters that can be used in hotels?
Air Source Water Heater is a new type of low carbon and environmentally friendly water heater. The operating cost of heat pump water heaters is only 1/4 of the cost of electric water heaters, which is very energy-saving and efficient. Originally, as a fourth-generation air water heater, its greatest feature is safety and money-saving! The operating costs of the air water heater are only 1/4 of the electric water heater, 1/6 of the gas water heater, 1/2 of the solar water heater, 2/3 of the fuel water heater and 3/5 of the gas heating system. The device absorbs the heat in the air to heat the cold water, and the cool air released does not pollute the environment and completely eliminates the safety risks such as flammability, explosion, electric shock and gas poisoning of ordinary water heaters.
1. The compressor compresses the low pressure refrigerant flowing back and converts it into a gas with high temperature and high pressure for discharge.
2. The high temperature and high pressure refrigerant gas flows through the copper pipe wrapped around the outside of the water tank, and the heat is passed through the copper pipe into the water tank. The cooled refrigerant becomes liquid under constant pressure and enters the evaporator after passing the expansion valve.
3. As the pressure of the evaporator is suddenly reduced, the liquid refrigerant is quickly evaporated into a gaseous state and absorbs a large amount of heat.
4. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator, the energy in the air is absorbed by the evaporator, the air temperature drops quickly, and cold air is released and released.
5. The refrigerant that has absorbed a certain amount of energy is then returned to the compressor and enters the next circuit.
