Refrigeration system with bypass valves

A refrigeration system comprising, in combination, an evaporator, control means controlling the flow of a liquid refrigerant at a reduced pressure to said evaporator for producing a gaseous refrigerant at a lower pressure and temperature in said evaporator, a compressor for receiving said gaseous refrigerant from said evaporator and compressing said refrigerant to produce a refrigerant at an increased temperature and pressure, a condenser remote from said compressor and evaporator for receiving said refrigerant at increasing temperature and pressure and condensed the same to a liquid, a receiver for receiving said condensed liquid refrigerant, first transport means normally supplying said condensed liquid from said receiver to said control means, second transport means supplying said condensed liquid from said control means to said evaporator, a first bypass valve for supplying gaseous refrigerant at said increased pressure and temperature to the interior of said receiver and bypassing said condenser when the pressure in said receiver falls below a predetermined value, a second bypass valve for supplying gaseous refrigerant at an increased pressure and temperature directly to said second transport means and bypassing said control means when the temperature in said evaporator falls below a predetermined value.
