A Comprehensive Guide to Industrial Heat Pump Technology

Refrigeration systems can run on a number of refrigerants but Ammonia for an all round application is the most versatile refrigerant, CO2 is a refrigerant that is really only suitable for low temperature applications.

The effective COP will depend on the heat pump inlet pressure and the discharge pressure that is required to deliver the needed water temperature, but the COP is likely to range between 4 and 8 (higher is possible depending on application).

The first stage of the industrial heat pump is providing refrigeration to the facility via a secondary refrigerant. The heat being rejected via this first stage is either rejected to the atmosphere or is directly introduced into the second stage depending on whether there is a hot water requirement.

Balance is crucial for heat pumps. It is important that you have a consistent heat source when refrigeration is required to work. It is imperative to map the refrigeration system load against the load profile for the heating requirement.
