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.

Does heat pump consume electricity a lot ?

The answer to this question is of great concern to consumers and JNOD's answer is that air source heat pumps are a very energy efficient new energy heating device, compared to other electric heating devices on the market.

Heat pumps require some electricity to operate, but the amount is relatively small. 

The air source heat pump type works by using a small amount of electricity to drive the compressor to run and put the whole heat pump system into operation.

Heat is continuously absorbed from the air through the evaporator. 

Finally the heat absorbed and the heat generated by the electricity consumed is transferred to the water through the condenser.

We usually measure the efficiency of a heat pump in terms of COP. 

This unit is determined by measuring the energy input (in this case, electricity) and the energy output (heat). 

A heat pump with a CoP of 3 can produce 3 kW of heat from every 1 kW of electricity. 

Modern heat pump systems can transfer three to four times more heat energy in the form of heat than they consume in electrical energy to do this job. 

Other electric heating products such as the boiler, which has a COP = 1, mean that as much electricity as you want to produce heat is consumed. 

So choose a product with a COP greater than 1 (JNOD's heat pump) and you'll save on your energy bills!

Furthermore, JNOD's heating and cooling heat pump has Inverter EVI technology, which will allow the heat pump to adjust its operating power according to the ambient temperature, which will be even better.

There are many different factors will influence on your heat pump's electricity consumption, for example lifestyle, size of heat pump, heating space size,etc. 

Don't hesitate to contact JNOD for further advice and discussion on heat pump.

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.
