There are refrigerant heat recovery systems that only recover the de-super heat energy of the refrigeration process. That is the highest temperature gasses typically coming off of the refrigerant compressor.
1. A consistent temperature energy source for the C-H heating units2. Continuous recovery and storage of heat from cooling loads for later heating use3. Use of low demand/carbon energy storage to supplement recovered cooling energy when required.
