摘要： A refrigeration system includes a compressor for compressing a gaseous refrigerant, such that the temperature and pressure thereof increases, whereas the boiling point thereof decreases; a condenser, in which the gaseous refrigerant from the compressor exchanges heat with a high temperature heat carrier, said heat exchange resulting in the refrigerant condensing; an expansion valve reducing the pressure of liquid refrigerant from the condenser, hence reducing the boiling point of the refrigerant; an evaporator, in which the low boiling point refrigerant exchanges heat with a low temperature heat carrier, such that the refrigerant vaporizes; and a suction gas heat exchanger exchanging heat between high temperature liquid refrigerant from the condenser and low temperature gaseous refrigerant from the evaporator. The low temperature gaseous refrigerant entering the suction gas heat exchanger contains a certain amount of low temperature liquid refrigerant, said low temperature liquid refrigerant vaporizing as a result of the heat exchange with the high temperature liquid refrigerant from the condenser. Disclosed is also a refrigeration method.

摘要： A plate heat exchanger without straight flow channels is provided, for exchanging heat between fluids. Said heat exchanger, comprises a start plate, an end plate and a number of heat exchanger plates provided with a pressed pattern of ridges and grooves with a pitch. The heat exchanger plates are kept at a distance from each other by contact between ridges and grooves of neighboring plates in contact points, when said plates are being stacked onto one another. Flow channels are thus formed between said plates, the contact points are positioned so that no straight lines are formed along the length of the heat exchanger plates.
