Refrigeration system with pressure-balanced heat reclaim

A refrigeration system with pressure-balanced heat reclaim, comprising:

• at least one compressor configured to discharge a compressed refrigerant;
• a heat reclaim branch having a first end configured to receive at least a first portion of the compressed refrigerant and a second end;
• a heat reclaim valve and a heat reclaim heat exchanger disposed between the first end and the second end of the heat reclaim branch, the heat reclaim heat exchanger configured to transfer heat from the compressed refrigerant to one or more heating loads;
• a condensing branch having a first end configured to receive at least a second portion of the compressed refrigerant and a second end, the second end of the condensing branch being fluidly coupled to the second end of the heat reclaim branch;
• a condenser and at least one condenser inlet valve disposed between the first end and the second end of the condensing branch;
• a pressure regulation device disposed between the heat reclaim heat exchanger and the second end of the heat reclaim branch;
• and
• a controller configured to send a first output signal to position the heat reclaim valve, and a second output signal to position the condenser inlet valve, and a third output signal to position the pressure regulation device to substantially balance a first refrigerant pressure in the heat reclaim branch downstream of the pressure regulation device with a second refrigerant pressure in the condensing branch downstream of the condenser.

A refrigeration system with pressure-balanced heat reclaim, comprising:

• at least one compressor configured to discharge a compressed refrigerant;
• a heat reclaim branch having a first end configured to receive at least a first portion of the compressed refrigerant and a second end, the heat reclaim branch having a first refrigerant pressure drop;
• a condensing branch having a first end configured to receive at least a second portion of the compressed refrigerant and a second end, the second end of the condensing branch being fluidly coupled to the second end of the heat reclaim branch, the condensing branch having a second refrigerant pressure drop;
• and
• a pressure regulation device disposed on one of the heat reclaim branch and the condensing branch and configured to substantially equalize the first refrigerant pressure drop and the second refrigerant pressure drop.
