This drawing below shows the logical topology of a standard refrigeration system and shows where the HotSpot heat recovery equipment (Heat Recovery Unit or HRU) is connected. The refrigeration cycle shown below would be applicable to a cooler, freezer, ice maker or air conditioner. If the unit were a heat pump, not shown is a 4-way valve (reversing valve) that would be located between the HotSpot connection and the condenser.
