Abstract
A refrigeration circuit (1) sequentially connected to a compressor (10), a condenser (11), an electric expansion valve (13), an evaporator (17), and an intake proportional valve (21). When the freezing capability of the refrigeration device is to be suppressed, a control means (30) will restrict the intake proportional valve (21) in order to place refrigerant in a discharge side of the evaporator (17) in a wet saturated steam state, and the electric expansion valve (13) will be set to an aperture such that the refrigerant in the interior of the evaporator (17) will be placed in the wet saturated steam state.
Claims4
A refrigeration device, comprising:
- a refrigeration circuit (1) sequentially connected to a compressor (10), a condenser (11), an electric expansion valve (13), an evaporator (17), and an intake proportional valve (21);
- a control means (30) that controls the capacity of the refrigerant circuit (1);
- and
- an command means (3) that provides indicators to the control means (30);
- wherein the control means (30) receives a request to control the capacity of the refrigerant circuit (1) from the command means (3), the intake proportional valve (21) will be restricted in order to place refrigerant in a discharge side of the evaporator (17) in a wet saturated steam state, and the electric expansion valve (13) will be set to an aperture such that refrigerant in an interior of the evaporator (17) will be placed in the wet saturated steam state.
