Bifunctional compression refrigerator

A bifunctional compression refrigerator located inside a building, wherein the refrigerator comprises:

• a thermally insulated cabinet equipped with an evaporator,
• a motor-driven compressor,
• a condenser,
• a temperature controller,
• a first temperature sensor, and
• a ventilation module,
• wherein the ventilation module comprises:
• a housing,
• an inlet ventilation pipe,
• an outlet ventilation pipe, and
• a fan,
• wherein the inlet ventilation pipe and the outlet ventilation pipe are arranged on the opposite sides of the housing,
• wherein the fan is installed inside the housing between the inlet ventilation pipe and the outlet ventilation pipe,
• wherein the housing is arranged on the thermally insulated cabinet,
• wherein the condenser is installed inside the housing, and
• wherein the housing is configured to have access to an outdoor air outside the building,
• wherein an inlet vent geometrically coupled to the inlet ventilation pipe and an outlet vent geometrically coupled to the outlet ventilation pipe are arranged inside the housing,
• wherein a first switching unit is arranged between the inlet vent and the inlet ventilation pipe, the first switching unit being configured;
• to open the inlet vent and to close the inlet ventilation pipe, and
• to close the inlet vent and to open the inlet ventilation pipe,
• wherein a second switching unit is arranged between the outlet vent and the outlet ventilation pipe, the second unit being configured:
• to open the outlet vent and to close the outlet ventilation pipe, and
• to close the outlet vent and to open the outlet ventilation pipe,
• wherein a second temperature sensor and a control unit are arranged on the thermally insulated cabinet, and
• wherein the control unit is integrated with the temperature controller.
