The invention discloses a refrigerator
refrigeration system. A varying temperature room I and a varying temperature room II are arranged in a refrigerator, an outlet of a compressor is connected withan inlet of a condenser, an outlet of the compressor is connected with an inlet of a dry filter, and an inlet of a
changeover valve is connected with an outlet of the dry filter; the two outlets are separately connected with inlets of a first
thin glass tube and a second
thin glass tube, an outlet of the first
thin glass tube is connected with an inlet of an
evaporator, and an outlet of the secondfirst thin
glass tube are separately connected with inlets of a second stop valve and a second
evaporator through a three-way
pipe; and an inlet of a first stop valve are separately connected with outlets of the first
evaporator and the second evaporator through a three-way
pipe, an inlet of the compressor is separately connected with outlets of the first stop valve and the second stop valve through a three-way
pipe, and a controller is used for controlling the opening and closing of the
changeover valve, the first stop valve and the second stop valve. The refrigerator
refrigeration system can solve the distribution problem of refrigerants during
refrigeration in different rooms, so that each room of the refrigerator can realize mutual conversion of refrigerating and freezing functions.
