Patent ID: 10883746

Abstract:
Apparatus including a refrigeration system, a geothermal system, and a refrigerant flow control apparatus connected between the refrigeration system and the geothermal system, wherein a first valve system is selectively actuatable to (i) in a first operation mode cause the refrigerant from a refrigerant circuit to flow through a first heat exchanger, with no refrigerant flow through a second heat exchanger, (ii) in a second operation mode cause the refrigerant from the refrigerant circuit to flow first through the first heat exchanger and then through the second heat exchanger in a first refrigerant flow direction, (iii) in a third operation mode cause the refrigerant from the refrigerant circuit to flow through the second heat exchanger, with no refrigerant flow through the first heat exchanger, and (iv) in a fourth operation mode cause the refrigerant from the refrigerant circuit to flow first through the second heat exchanger and then through the first heat exchanger in a second refrigerant flow direction.
