Frequently Asked Questions of Heat Pumps

What is a heat pump and why we choose it to heat and cool?

What is a heat pump?

A heat pump is an electrical device that extracts heat from one place and transfers it to another. The heat pump is not a new technology; it has been used around the world for decades. Refrigerators and air conditioners are both common examples of this technology.

Heat pumps transfer heat by circulating a substance called a refrigerant through a cycle of evaporation and condensation (see Figure 1). A compressor pumps the refrigerant between two heat exchanger coils. In one coil, the refrigerant is evaporated at low pressure and absorbs heat from its surroundings.The refrigerant is then compressed and sent to the other coil, where it condenses at high pressure. At this point, it releases the heat it absorbed earlier in the cycle.

Refrigerators and air conditioners are both examples of heat pumps operating only in the cooling mode. A refrigerator is essentially an insulated box with a heat pump system connected to it. The evaporator coil is located inside the box, usually in the freezer compartment. Heat is absorbed from this location and transferred outside, usually behind or underneath the unit where the condenser coil is located.Similarly, an air conditioner transfers heat from inside a house to the outdoors.

The heat pump cycle is fully reversible, and heat pumps can provide year-round climate control for your home heating in winter and cooling and dehumidifying in summer. Since the ground and air outside always contain some heat, a heat pump can supply heat to a house even on cold winter days. In fact, air at –18°C contains about 85 percent of the heat it contained at 21°C.

A heat pump water heater can heat or cool , the heating function is used the most, and commonly used for house heating, domestic hot water or swimming pool water heating. It absorbs heat from air or ground, then transfers the heat to water for pool water heating, room heating by radiator, underfloor coil or water fan coil.

According to the souce of the heat , there are two types of heat pump water heater, one is air source heat pump and the other is ground source (also called earth energy, geothermal) heat pump. An air source heat pump absorbs heat from the outdoor air in winter and rejects heat into outdoor air in summer. It is the most common type of heat pump found in homes at this time. A ground source heat pump which draws heat from the ground (soil, rock) or water (underground water, river, lake), are also becoming more widely used.

Why we choose it to heat and cool?

Heat pump is a low-carbon energy-saving product, it is high efficiency, energy-saving, safe and reliable, environmentally friendly, intelligent and durable. It can be used all year round the year. The use of heat pump will not be influenced by bad weather such as overcast, rain, snow, and it does not produce any exhaust gas, waste water and waste residue emissions.

The operation cost of heat pump water heater is only 1/4 of the electric water heater, 1/3 of the oil and gas water heater, and 1/2 of the solar water heater, therefore installing a heat pump is an effective way to reduce our energy costs.
How many types of air source heat pump do we have?

Usually, we say air source heat pump for the heat pumps whose heat source is air, which means they absorb heat from the air and transfer the heat to water. However, there are different types of air source heat pumps if we classify them based on the application and the different technology used on the heat pumps.

Based on the application, air source heat pumps includes air source heat pump for swimming pool water heating (usually we call it swimming pool heat pump) and air source heat pump for house heating or domestic hot water. Based on the different compressor technology, there are on-off (constant frequency) air source heat pump, DC inverter air source heat pump and EVI air source heat pump which works at minus 25 degree.
How does the EVI heat pump compressor work?

Copeland EVI Scroll compressors are equipped with a vapor injection connection for Economizer Operation. Economizing can be accomplished by utilizing a subcooling circuit similar to the circuit shown in Figure 1. This increases the refrigeration capacity and the system efficiency. The benefits provided will increase as the compression ratio increases.

The schematic shows a system configuration for the economizer cycle. A heat exchanger is used to provide additional subcooling to the refrigerant before it enters the evaporator. This subcooling process provides the increased capacity gain measured in the system. During the subcooling process, a certain amount of refrigerant is evaporated. This evaporated refrigerant is injected into the compressor and provides additional cooling at higher compression ratios.

The P-h diagram (Figure 2) shows the theoretical gain in system performance acquired by using the economizer cycle. The extension outside of the vapour dome provides the enthalpy increase, enhancing system performance. Although power increases due to the vapour injection into the compressor, there is still a significant efficiency gain because the capacity gain exceeds the power increase.

With the EVI heat pump compressor technology, the EVI heat pump is able to work down to -25℃ the minimum. It works efficiently in heating to provide stable and comfortable heating or hot water for our house.
How to work out the swimming pool heat pump's heating capacity needed for our pool?

It is complicated to work out the heating capacity needed for the swimming pool, if we base on the strict calculation way with all factors considered inside. It's not an easy things for people who are not in the field of heat pumps. Here we'll introduce a simple way to help you to work out the heat capacity needed for our swimming pool.

Before the calculation , we need to know the pool size, the initial pool water temperature (usually equal to the ambient temperaure) and the target water temperature. The following is the calculation formula.

Heating demand of the swimming pool = C * 1.163 * △t / T

Where:

C = cubage of the swimming pool water ( in m3 )

△t = target water temperature - initial water temperature

( for instance, if you want to heat the pool water from 20℃ to 30℃, the △t = 30℃ -20℃ = 10℃ )

T = heating duration ( we can choose 24 hours, 48 hours or 72 hours, the shorter the time, the quicker the pool water becomes hot, as the heating power of the swimming pool heat pump will bacame larger accordingly)

If we want to heat up the pool water in short time, we can put the heating duration short, then the heat capacity of the swimming pool heat pump will be larger. The heating duration is the first time to heat up the swimming pool, as usually there is thermal insulation for the swimming pool, the following heating duration will be less than the first time if the thermal insulation is well made.

With the above instruction , it will help us to work out the swimming pool heat pump suitable for our pool size.
What are the advantages of the DC inverter heat pump?

DC inverter heat pump becomes a trend and popular in recent years. It is well known because of its changeable running frequeny, then what advantages do the dc inverter heat pump has? The DC inverter heat pump is with soft start, so the starting current is low. It can work down to -25℃, provides us with comfortable and constant water temperature. It is high efficiency, energy saving, environment friendly, as well low noise.

1) Soft start, low starting current

With soft start function , the heat pump can start smoothly and so reduce the starting current to avoid the trip due to the overcurrent. Besides, because there is no current impacting on the compressor, the lifespan of the DC inverter heat pump machine is prolonged.

2) Comfortable and constant water temperature

The running frequency of the inverter heat pump compressor is automatically adjusted based on the change of the ambient temperature and water temperature. When the ambient temperature is low, the compressor runs in high frequency and the target water temperature is reached quickly. When the ambient temperature is high, the compressor decreases the running frequency and runs in low frequency to keep the water temperature stable. Thus the room temperature or hot water temperature is always comfortable and constant.

3) High efficiency and able to work down to -25℃

As the variable running frequency at the different ambient temperature, it makes the DC inverter heat pump more adaptable to work in low temperature environment and work down to -25℃, meanwhile make sure the efficient heating at low temperature.

4) Low noise

There is no frequent start and stop on the heat pump machine so it is not only less noise but also energy saving. Besides, when the DC inverter heat pump runs in low frequency , the noise is also relatively low, so it provide us more quiet and comfortable environment.

5) Energy saving and environment friendly

As any of other types of the heat pumps , DC inverter heat pump is a low-carbon energy saving product. It does not produce any exhaust gas, waste water and waste residue emissions. The operation cost of the DC inverter heat pump is only 1/4 of the electric water heater, 1/3 of the oil and gas water heater, and 1/2 of the solar water heater, therefore installing a DC inverter heat pump is an effective way to reduce our energy costs.
