What's the HS Code of heat pump ?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't provide HS Code or we give...

How to set water temperature for the air source heat pump ESD series ?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...

What are the advantages of the EVI heat pump ?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 guarantees the heating e...

What are the advantages of the DC inverter heat pump ?DC inverter heat pump bacomes 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 temperatu...

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 pump. Here we'll introduce a simple way to help you to work out the heat capacity needed f...

How does the EVI heat pump compressor work ?Copeland EVI Scroll compressors are equipped with a vapour injection connection for Economizer Operation.Economizing can be accomplished by utilising 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. Th...

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 , that means they absord heat from 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...

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 call...
