In the Heating and Cooling Heat Pump structure, the refrigerant directly exchanges heat with the air to be treated, without secondary heat exchange in the middle, which reduces the intermediate heat exchange links, which can effectively reduce the energy consumption of the system and improve the heat exchange efficiency.

What is the technological advancement of Heating and Cooling Heat Pump compared to traditional air conditioners?

The refrigeration principle of the traditional air conditioner is to use the change of the physical state of the refrigerant. The change from the gaseous state to the liquid state will emit heat, and the change from the liquid state to the gaseous state will absorb heat. The "reverse Carnot" cycle used for Heating and Cooling Heat Pump is opposite to the refrigeration principle of traditional air conditioners. Using a "four-way electromagnetic reversing valve", a refrigeration cycle or a heating cycle can be realized, so that the car can get cold or hot air. . In the cycle of air-conditioning refrigerant, a large amount of heat will be released during the process of liquefying high-temperature and high-pressure gas into high-pressure liquid in the condenser, which is the principle of heat pump heat release. In winter, the reversing valve can be used to change the flow direction of the air-conditioning refrigerant. At this time, the evaporator acts as a condenser to release heat in the reverse cycle, forming a "heat source". At this time, only a small amount of electricity is consumed, and a large amount of heat from the outside can be transported and "pumped" into the pure electric vehicle to become a heat pump. However, the heating effect of heat pumps in low temperature environments needs to be improved.

Where can Heating and Cooling Heat Pump be used?

The heating principle of Heating and Cooling Heat Pump is completely different from that of traditional solar water heaters. Air source heat pumps use air, water, solar energy, etc. as low-temperature heat sources. The hot water is directly sent to the user through the circulation system as hot water supply or small area heating using fan coil units. Heating and Cooling Heat Pump is the best solution for large, medium and small hot water centralized supply systems in school dormitories, hotels, bathing centers and other places.

Why does Heating and Cooling Heat Pump become the choice of more and more consumers?

Heating and Cooling Heat Pump is one of the most advanced energy utilization products in the world today. With the rapid development of the economy and the improvement of people's living standards, hot water for domestic use has become a necessity for people's lives. However, traditional water heaters (electric water heaters, fuel-fired water heaters, and gas water heaters) have disadvantages such as high energy consumption, high cost, and serious pollution; The operation of energy-saving and environmentally friendly solar water heaters is restricted by meteorological conditions.

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. 

Any question or idea please don’t hesitate to inquire JNOD!

As heat pumps are more and more popular in the market, people want to know if it's worthy to use it.

Of course Yes! Heat pump water heaters are worth the cost.

More Efficient

Heat pumps are significantly more energy efficient than normal electric or gas hot water heaters because instead of using energy to generate new heat, they collect existing ambient warmth and transfer it to the water. This efficiency can save you hundreds of dollars on energy bills each year.

Tax Incentives and Rebates

With tax incentives and state-sponsored sales rebates, energy efficient heat pump water heaters can actually be a more affordable choice than most homeowners would expect. Though the upfront cost is high, most homeowners pay back heat pump water heaters within the first or second year alone. And heat pump water heaters are long-lasting –  a good, well-maintained heater can last between ten to fifteen years.

Environmentally Friendly

Because heat pumps are more energy efficient than conventional hot water heaters, they do not use as much electricity and/or natural gas, which reduces greenhouse gas emissions. In fact, it estimates that if all residential water heaters were replaced with heat pump water heaters, there would be up to 140 billion pounds of greenhouse gas emissions are saved annually.

Winter has arrived, and people tend to use heat pumps as heating machines. If the heat pump unit can be installed reasonably, the service life and heating capacity of the heat pump will be improved. Let Jnod tell you how to install it, see below:

1. Unit installation location planning

1) The installation requirements of the heat pump main unit are similar to the installation requirements of the outdoor unit of the air conditioner. It can be installed on the roof, balcony, and ground. The air outlet should avoid the windward direction.

2) The distance between the main unit (wind from the side) and the surrounding walls or other obstructions should not be too small. There should be no obstructions within 1 meter of the air outlet, and ensure that the heat exhaustion and suction of the heat exchanger are not hindered.

3) There should be no obstructions within 1 meter of the air inlet of the main unit (top air outlet), and no obstructions within 2 meters of the air outlet to ensure that the heat exhaustion and suction of the heat exchanger of the main unit are not hindered.

When the unit is installed under the eaves or there are horizontal obstacles above the unit, the installation location of the unit must be in a well-ventilated place, otherwise it is easy to short-circuit the air flow, resulting in poor heat dissipation capacity of the unit.

2. Unit installation environment control

1) Try not to place it in direct sunlight.

2) Not on the window sill of the bedroom or near the bedroom.

3) There is enough distance between the air inlet and outlet to facilitate heat dissipation.

4) Places that can withstand more than 2-3 times the weight of the outdoor unit.

5) A place where there is no oily smoke or other corrosive gas.

6) A place that does not affect other factors or the environment.

Heat pump water heater is a new type of water heater. It converts air energy into heat energy through a heat pump to produce hot water. This water heater solves the disadvantage that solar energy cannot be used on rainy days. In addition, this water heater is more efficient compared to gas water heaters and electric water heaters. Environmental protection when you choose this water heater is a very good choice.

What is the main reason why air heat pump water heaters are popular in the market?

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.

What is the workflow of a heat pump water heater?

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.

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.
