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

When a general air conditioner is refrigerating, it absorbs the heat in the room through the phase change of the refrigerant in the evaporator (liquid to gas), and then realizes cooling through the heat release of the outdoor condenser. His heat exchange equipment is mainly finned heat exchangers. The heat pump water heater converts the low-grade energy in the air into high-grade energy that we can use. The heat is obtained by absorbing heat from the air through the phase change (endothermic) of the refrigerant in the evaporator, and then releasing heat through the indoor condenser (or jacket heat exchanger). This is his heating state. Its cooling is the same as that of general air conditioners, except that the heat exchanger may be different. General air conditioners use ordinary finned heat exchangers.

What are the advantages of heat pump water heater and compared with gas water heater?

Gas water heaters heat the water temperature by burning combustible gas, and at the same time, will produce greenhouse gases such as carbon dioxide. If the continuous large amount of carbon dioxide on the earth exists in the air for a long time, it will produce a greenhouse effect on the earth's environment! The heat pump water heater only heats the water temperature with the heat in the air, and will not emit any toxic and harmful gases. In the era of energy saving and emission reduction, it is a water heater that is truly energy-saving and environmentally friendly. Secondly, gas water heaters may leak gas and cause human carbon monoxide poisoning accidents. Therefore, the safety of empty heat pump water heater is better than that of gas water heater.

What are the advantages of heat pump water heater compared to electric water heater?

We can compare heat pump water heater with electric water heater. Electric water heaters are heated with electric heating rods. The heat pump water heater heats the water temperature by absorbing heat from the air. The heat generated by the heat pump water heater consumes 1 kWh of electricity equivalent to the heat generated by the electric water heater consuming 4 kWh of electricity. In terms of energy saving, heat pump water heaters are far more energy efficient than electric water heaters. Second, in terms of security. The heat pump water heater just transfers the heat after compression heating to the water tank for heating, so the water and electricity are completely isolated. The electric water heater electric heating rod is directly heated in the water. Therefore, leakage accidents are easy to occur!

A heat pump is part of a heating and cooling system. Like an air conditioner, 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.

HOW A HEAT PUMP WORKS

A.COOLING MODE

One of the most important things to understand about heat pump operation and the process of transferring heat is that heat energy naturally wants to move to areas with lower temperatures and less pressure. Heat pumps rely on this physical property, putting heat in contact with cooler, lower pressure environments so that the heat can naturally transfer. This is how a heat pump works.

B.HEATING MODE

A Heat pump in heating mode operates just like cooling mode, except that the flow of refrigerant is reversed by the aptly named reversing valve. The flow reversal means that the heating source becomes the outside air (even when outdoor temperatures are low) and the heat energy is released inside the home. The outside coil now has the function of an evaporator, and the indoor coil now has the role of the condenser.

The physics of the process are the same. Heat energy is absorbed in the outdoor unit by cool liquid refrigerant, turning it into cold gas. Pressure is then applied to the cold gas, turning it to hot gas. The hot gas is cooled in the indoor unit by passing air, heating the air and condensing the the gas to warm liquid. The warm liquid is relieved of pressure as it enters the outdoor unit, turning it to cool liquid and renewing the cycle.

Now, more and more families are making the preparation for the Winter, Like installing the heat pump for house heating and hot water.

What role does the refrigerant play in the unit composition of the heat pump water heater?

The heat pump unit contains a special heat-absorbing refrigerant. In the liquefied state, the normal temperature is below minus 20°C. Therefore, there is a temperature difference between it and the outside temperature. The refrigerant absorbs the outside temperature and is stored in the evaporator. Generate pressure and evaporate and evaporate, and through the work of the heat exchanger (heat pump), when the refrigerant is transferred from the evaporated state to the liquefied state, the objectively existing heat is released to the storage water in the water tank.

What is the physical principle of how a heat pump water heater works?

The heat pump water heateruses the heat absorbing medium (refrigerant) in the device to collect heat energy from the air or the natural environment, heats the cold water quickly through the heat exchanger and at the same time releases the cold air, avoiding the lack that conventional solar products can not work in rainy weather and at night. As long as the outside temperature is above 1-15 degrees, it can work normally, so can be more efficient and energy-saving, at the same time does not occupy open space, and is easy to install and flexible to use.

What is the significance of the appearance of heat pump water heaters?

With the rapid development of the economy and the improvement of people's living standards, water heating has become a necessity for people's lives. However, conventional electric water heaters have the disadvantages of large energy consumption, high cost and serious environmental pollution; while the operation of energy-saving and environmentally friendly solar water heaters is also restricted due to weather conditions. The heating principle of the air heat pump is different from that of the conventional solar water heater. The air heat pump uses air, water, solar energy, etc. as a low temperature heat source, and the air heat pump uses the electrical energy as energy to absorb heat from the low temperature side to heat the service water.

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?

How does the heating and cooling heat pump work?

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.

What does the operating time of the heating and cooling heat pump have to do?

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.

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.

Swimming Pool Heat Pump Benefits

Reliable and durable heat pumps require fewer repairs than gas heaters.

No emissions and low electrical use make heat pumps the eco-friendly pool heater.

Heats for much lower costs, costing 50-75% less than gas heaters to operate.

How Swimming Pool Heat Pumps Work:Swimming Pool heat pumps leverage a combination of air and electricity to heat your pool water. They use electricity to power a fan and a small compressor, to absorb surrounding air heat and transfer it into your pool’s water. Pool heat pumps require very little electricity to run.

Swimming Pool Heat Pump Installation: Heat pumps can be purchased, placed level and plumbed after the filter by any handy homeowner, but we recommend an electrician to come in for the power hook-up.

Swimming Pool Heat Pump Operation Cost: The cost to operate a heat pump depends on many factors such as size of Swimming pool, size of heat pump and the outside air temperature. When the air temperatures are colder, the fan and compressor must run longer to maintain temperature, but during warmer periods the heat pump may need to run only an hour per day to maintain water temperature.

For the swimming pool heat pump, we have both R32 and R410A model. The heating capacity can be made from 3KW to 97.5KW. ON/OFF and inverter model,residetial and commercial are available. It’s with 4 ways valve,provide both heating and cooling mode to create more possibility for pool enjoyment.

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.
