Abstract:
1. A secondary cooling loop system for use in an air conditioning system of a body to be cooled, comprising: (a) a heat exchanger having a first expansion coil for circulating a refrigerant therethrough and a second expansion coil having an inlet and an outlet for circulating a refrigerant therethrough; (b) a cooling unit for cooling the solution as it circulates therethrough, the cooling unit having an inlet and an outlet, wherein the inlet is in fluid communication with the second expansion coil of the heat exchanger; (c) a reservoir for storing the solution, the reservoir having an inlet and an outlet, wherein the inlet is disposed in fluid communication with outlet of the cooling unit; (d) a return line for returning the stored solution from the reservoir back to the inlet of the second expansion coil of the heat exchanger, the return line being disposed in fluid communication with the first outlet of the reservoir and with the inlet of the second expansion coil of the heat exchanger; (e) a by-pass line disposed between the outlet of the cooling unit and the second expansion boil of the heat exchanger for bypassing the reservoir and delivering the solution directly from the outlet of the cooling unit to the inlet of the second expansion coil of the heat exchanger; (f) a first valve disposed in the bypass line between the outlet of the cooling unit and the inlet of the second expansion coil of the heat exchanger, wherein the first valve opens to deliver the solution directly from the outlet of the cooling unit to the inlet of the second expansion coil of the heat exchanger, thereby bypassing the reservoir; and (g) a connecting line disposed between the outlet of the cooling coil and the inlet of the reservoir, and a second valve disposed in the connecting line, wherein the second valve opens when the first valve closes to allow the solution to flow into the inlet of the reservoir.
