What is the operating mode and principle of the unit composition of the heat pump water heater?

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.

What are the benefits of installing a heat pump water heater?

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.

What is the difference between a heat pump water heater and an air conditioner?

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.

How to choose a truly eco-friendly Swimming Pool Heat Pump?

The initial heating determines the model selection. The real energy saving stage of the Swimming Pool Heat Pump depends on the "constant temperature" period.

Select frequency conversion, more energy saving, the key to Swimming Pool Heat Pump lies in the operation logic of frequency conversion technology. In the constant temperature stage, the frequency conversion technology can enable the equipment to operate intelligently at a low frequency and match the real-time heating demand. There is no need to continuously heat the pool water by repeatedly starting and stopping like a fixed-frequency heat pump, so as to achieve the purpose of energy saving. We can compare the energy saving performance of fixed frequency heat pump and variable frequency heat pump under the same conditions.

Due to the difference in temperature, the heating efficiency of the heat pump will also be different. To compare the energy-saving effect in the constant temperature stage, we chose a fixed-frequency heat pump with the same heating level as the variable-frequency heat pump (IPHC150T) selected in the previous step at an air temperature of 26 °C (26 °C is generally used as the test temperature in the laboratory). Frequency selection is 60kw.

What is the function of the Swimming Pool Heat Pump damping system?

① The independent suspension shock absorption system makes the fan and motor run more quietly and reduces the noise caused by air disturbance.

② An integral base carries the fan and the motor, and according to the load-bearing distribution of each part, different types and quantities of shock absorbers are correspondingly configured to avoid jumping, anti-vibration and resonance, and make the operation of the fan and the motor more stable.

③ The fan and the box are isolated by flexible connection to avoid vibration transmission.

Why choose an energy-efficient Swimming Pool Heat Pump?

Considering indoor air quality, Swimming Pool Heat Pump is equipped with fresh air treatment function and exhaust function.

Considering the operating cost of the constant temperature heat removal pump unit, the Swimming Pool Heat Pump can use a large amount of outdoor low-humidity fresh air to adjust the humidity of the indoor air in spring and autumn, reducing operating costs.

In order to prevent the circulating air from affecting the service life of the Swimming Pool Heat Pump, the key components and sheet metal structure of the equipment are treated with anti-corrosion during the manufacturing process, and the compressor, power distribution cabinet and control system are isolated from the wind system.

How to choose a swimming pool heat pump?

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.

Simple & General Method

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.

Accurate calculation Method

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
Power Input (kW)	0.27~2.81	0.29~3.26	0.31~3.89
COP	16.1~6.4	16.2~6.5	16.2~6.5
Ambient Temperature：（DB/WB）15℃/12℃；
Heating Capacity (kW)	3.44~13.35	3.51~14.21	3.81~17.08
Power Input (kW)	0.41~2.61	0.43~2.78	0.48~3.35
COP	8.3~5.1	8.1~5.1	8~5.1

Hope this can help you choose suitable models for swimming pool.

How energy efficient is the Heating and Cooling Heat Pump?

The Heating and Cooling Heat Pumpcan adjust the indoor temperature by absorbing the heat energy in the air and then transferring it to the water for heat exchange. In summer, it is cooled by fan coil unit, and in winter, it is heated by fan coil unit, floor heating or radiator. It has a dual-purpose function. Heating and Cooling Heat Pump can also be connected in areas with better environment. Domestic hot water, and even the water heater are saved.

How to save resources when cooling with Heating and Cooling Heat Pump?

Heating and Cooling Heat Pumprefrigeration is to cool the circulating water in the pipeline into chilled water through the heat pump unit. The outlet air temperature of the indoor fan coil is between 15°C and 20°C. The chilled water is circulated into the room for heat exchange, and the evaporator The heat absorption in the room transfers the heat in the room to the circulating water in the pipeline, and then the circulating water after the heat absorption is brought to the heat exchanger configured by the heat pump unit through the operation of the water pump for heat exchange, and finally the heat pump host discharges the heat to the air In the cycle, this process is repeated to achieve the effect of indoor cooling. However, it should be noted that after the circulating water in the pipeline is cooled by the Heating and Cooling Heat Pump, the temperature can be kept stable for a long time without heat exchange, and there is no short-term loss of cooling capacity. Energy consumption will also be lower.

How to save resources when heating with Heating and Cooling Heat Pump?

Heating and Cooling Heat Pump heating is to replace the collected heat into the heating pipeline through the heat pump unit, and then deliver the water to the floor heating, fan coil and radiator at 35°C-45°C, 40°C-50°C and 55°C respectively. The heat is released in the middle, so as to achieve the effect of indoor heating. Because the air energy heat pump adopts frequency conversion technology and jet enthalpy increasing technology, it has a high energy efficiency ratio, and can obtain more than three times the heat energy from the low temperature environment, and the energy saving performance will be much higher than that of direct conversion of electric energy into heat energy.

How does the heating and cooling heat pump work?

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.

How exactly does the heating and cooling heat pump work?

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.

What is the basic principle of heating and cooling heat pump?

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.

Will the floor height affect the installation of the 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.
