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 ca...

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,...

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 r...

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....

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 t...

Low temperature air source EVI heat pump is widely used in the cold region of Europe. It adopts EVI compressor, of which the heating efficiency is 50%~80% higher than the conventional air source heat pump at low temperature. When the ambient temperature drops significantly, the attenuation of the heat power is very small, this guarantee...

The water temperature of the heat pumps is usually set in the commissioning in factory. But some end users want to set the target water temperature as they desire and need, so here we put the instruction on the water temperature setting for theire easy use. This instruction applies to the swimming pool heat pump ESDPH series and house h...

The full name of HS Code is International Convention for Harmonized Commodity Description and Coding System. Simply, it is Harmonized System and we usually call it HS Code for short.Heat pump HS Code is usually required for importing or exporting in the internaltional business. The import & export process can not go smoothly if we don...
