Large Scale Heat Pump
Description
As with high-temperature heat pump, the definition of large scale heat pump is not clear and is often use for heat pump with a heat capacity of at least 500 kW or 1 MW. The fundamental of large heat pump is not different than normal heat pump, the components are just much larger. The are designed to be used in the industrial sector or for heating district. The market is currently not large and thus only a couple of manufacturer offer large heat pumps. The table below shows some manufacturers. Large heat pumps have their own challenges such as transportation from the production to the implementation location, security issues depending on the refrigerants, vibration and weight of the system, and as well electrical connection. The European Heat Pump Association (EHPA) have written two reports on large scale heat pumps in Europe.
Examples
There are a few large heat pumps installed and running in Switzerland with more than 1 MW of heating capacity:
