Problems solved by technology

This is exit logic because the outer flow channel in the plate pack has only one heat exchange plate surface, while the middle flow channel will exchange heat through the two heat exchanger plates that limit the flow channel, which means that it is impossible to accurately measure the refrigerant temperature in the channel

Abstract

A brazed plate heat exchanger comprises a number of heat exchanger plates (100) provided with a pressed pattern comprising ridges (R) and grooves (G). The ridges and grooves of neighboring plates contact one another in order to keep the plates on a distance from one another under formation of inter-plate flow channels for media to exchange heat when the heat exchanger plates are placed in a stackto form the heat exchanger. Means (120a, 120b) are provided for allowing temperature measurement of a fluid present in a second flow channel counted from an end of the stack of heat exchanger plates (100).

Description

technical field [0001] The present invention relates to a brazed plate heat exchanger comprising a plurality of heat exchanger plates provided with a pressed pattern comprising ridges and grooves, when the heat exchanger When the plates are stacked to form a heat exchanger, said ridges and grooves of adjacent plates contact each other to keep the plates spaced from each other to form inter-plate flow channels for the heat exchange medium. Background technique [0002] Brazed plate heat exchangers are commonly used as evaporators and / or condensers in heating and cooling applications where refrigerant is compressed, condensed and evaporated for evaporation with a low temperature source and condensation with a high temperature source. [0003] To control such systems, a controllable drive source for the compressor that compresses the gaseous refrigerant and a controllable drive for controlling the pressure between the high-pressure side (where the refrigerant is condensed) and ...
