Abstract

An improved refrigeration system, being of the compressor type and comprising all the main generic elements, which are the condenser, the refrigerant collection bottle, the heat exchanger and the evaporator, with its corresponding expansion valve, it is essentially characterized in that it comprises a water tank inserted in its circuit through which pass two coils coming from the high and low lines, respectively, the entrance to the low being governed by a reducing valve and also penetrating a bypass that goes directly to the intake of the compressor, controlled by a reducer and a solenoid and because its discharge line, at the entrance to the condenser, has a bypass that puts it in direct communication with the coolant collection bottle, without going through the aforementioned condenser, governed this step by the set of three valves, of which one, that s it only opens if the compressed gas has reached a certain pressure and that once opened does not offer any resistance to its passage, is located at the entrance of the condenser and the others, which are two check valves loaded at a reduced voltage, are placed for prevent the gas from entering the condenser by discharging it and to prevent the return of gas from the bottle to the discharge line, respectively, with the purpose of the latter also preventing the passage of compressed gas through it, when the valve it governs the passage to the condenser is open, depending on the resistance that opposes its spring to the passage of the same and which opposes the pressure of the gas to the output of the condenser, which adds to the aforementioned.
