The principle of heat pump chiller and industrial chiller is exactly the same. Heat pump is a refrigeration system that provides heat with the heat released by the condenser or other components. In principle, any cycle that can be used as a chiller can be used as a heat pump cycle, and any analytical method used for a chiller can be used to analyze a heat pump. For a combined machine that cools and heats at the same time, it can be called either a heat pump or a chiller. Generally speaking, there are two main differences between the two:

1. The purpose of the two is different: the energy interaction between a heat pump or an industrial chiller and the surrounding environment is to absorb heat from a low-temperature heat source, and then release heat to a high-temperature heat source. Its purpose is to obtain high temperature (heating) , that is, the part that releases heat to high temperature, that is, the heat pump;

If the purpose is to obtain low temperature (refrigeration), that is, to absorb heat from a low temperature heat source, it is an industrial chiller; due to different purposes, the economic indicators of heat pumps are different from those of chillers.

2. The working temperature areas of the two are often different: the so-called high temperature heat source and low temperature heat source are only relative to each other. Due to the different purposes of the two, usually heat pump water heaters use the environment as a low-temperature heat source, while chillers use the environment as a high-temperature heat source. Therefore, for the same ambient temperature, the working temperature area of ​​the heat pump is significantly higher than that of the industrial chiller.
