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.
Claims5
A refrigeration device, comprising:
- a refrigeration circuit being sequentially connected to a compressor, a condenser, an electric expansion valve, an evaporator, and an intake proportional valve;
- a control means for controlling the capacity of said refrigerant circuit;
- and
- a command means for providing indicators to said control means;
- said control means being configured to receive a request to control said capacity of said refrigerant circuit from said command means, said intake proportional valve being configured to be restricted to place refrigerant in a discharge side of said evaporator in a wet saturated steam state, and said electric expansion valve being configured to be set to an aperture to place refrigerant in an interior of said evaporator in said wet saturated steam state.
