Heat recovery system & plumbing diagrams
for our most popular configurations:


  1 compressor, connected to main tank, with adapter   1 compressor, pre-heat tank with adapter 1 compressor, pre-heat tank, plumbed
  2 compressors & pre-heat tank with adapter   1 compressor, connected to main tank, plumbed 2 compressors & pre-heat tank, plumbed
  2 compressors/2 units & single professional pre-heat tank   2 compressors with dual heat recovery unit, single pro tank
 

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.

Key:
The red dots represent hot high pressure refrigerant gas.
The solid red represents warm high-pressure refrigerant liquid.
Solid blue represents cold low pressure refrigerant liquid.
The blue dots represent warm low pressure refrigerant gas
The HotSpot connects at the hottest point, next to the compressor discharge.
