2results about How to "Adjust cooling capacity" patented technology

This invention discloses an evaporator for an adsorption refrigeration machine and the adsorption refrigeration machine itself, comprising: a cooling medium inlet and a cooling medium outlet; a liquid refrigerant inlet and a gaseous refrigerant outlet; at least one cooling medium flow plate for supplying cooling medium flow, each cooling medium flow plate being connected to both the cooling medium inlet and the cooling medium outlet; and at least one refrigerant flow plate for supplying refrigerant flow, each refrigerant flow plate being connected to both the liquid refrigerant inlet and the gaseous refrigerant outlet. The refrigerant flow plates and cooling medium flow plates are alternately stacked. This evaporator is a plate evaporator. By alternately stacking the cooling medium flow plates and refrigerant flow plates, plate cavities are formed between any adjacent cooling medium flow plates and refrigerant flow plates, creating alternating cooling medium flow spaces and refrigerant flow spaces. This achieves interactive heat exchange between the refrigerant and the cooling medium, resulting in a cooling effect. It has a high heat transfer coefficient, low thermal resistance, and high evaporation efficiency.

This disclosure provides an air conditioning system for engineering machinery. The air conditioning system includes a cooling circuit and a bypass branch. The cooling circuit includes a compressor, a condenser, a throttling and pressure-reducing device, and an evaporator, which are sequentially connected and form a loop. The bypass branch includes a first bypass control valve and a second bypass control valve. One end of the first bypass control valve is connected between the exhaust port of the compressor and the condenser, and the other end of the first bypass control valve is connected to one end of the second bypass control valve. The other end of the second bypass control valve is connected to the inlet of the evaporator. The first bypass control valve is a normally closed solenoid valve, and the second bypass control valve is a hot gas bypass valve. The air conditioning system provided by this disclosure can reduce the start-stop frequency of the compressor and reduce the wear of internal compressor components.
