Abstract: A plate package made according to the method includes first heat exchanger plates and second heat exchanger plates. Each heat exchanger plate has a first porthole, and the port hole of at least one of the heat exchanger plates is surrounded by a peripheral rim. The first heat exchanger plates and the second heat exchanger plates, are joined to each other and arranged side by side in such a way that the peripheral rims together define an inlet channel extending through the plate package. The peripheral rim of the first and/or the second heat exchanger plates has at least one through hole, forming a fluid passage allowing a communication between the inlet channel and the first plate interspaces. The at least one through hole is made in a condition in which the first and the second heat exchanger plates have been joined to each other to form the plate package.

At least two injectors are provided, each injector being arranged to supply a first fluid to at least one of the first plate interspaces in the at least one plate package and at least one valve is arranged to control the supply of the first fluid to the at least two injectors.

Abstract: A plate heat exchanger includes a plate package having first and second heat exchanger plates. The plates are joined to each other and arranged side by side so that a first plate interspace exists between each pair of adjacent first and second heat exchanger plates, and a second plate interspace is formed between each pair of adjacent second and first heat exchanger plates. The first and the second plate interspaces are separated from each other and provided side by side in an alternating order. Substantially each heat exchanger plate has at least a first porthole forming a first inlet channel to the first plate interspaces. At least two injectors are arranged in a wall portion of the first inlet channel and extend from the exterior of the plate package to the first inlet channel interior, and each injector supplies a fluid to more than one of the first plate interspaces.

Abstract: The present application relates to a system for dynamic control of the operation of a heat exchanger, the system comprising a heat exchanger, a plurality of injector arrangements, a local sensor arrangement, and a controller, wherein the local sensor arrangement comprises a plurality of local temperature sensors being arranged to measure temperature values; and wherein the controller is arranged to determine a difference between the measured temperature values and is further arranged to communicate with the valves of the plurality of injector arrangements to adjust the local amount of first fluid supplied by at least one of the injector arrangements in order to even out the determined difference. The application also relates to a method for the dynamic control of the operation of a heat exchanger in such a system.

Abstract: A plate heat exchanger, which comprises a stack of heat transfer plates (2A; 2B) and is intended for evaporation of a liquid, e.g. refrigerant, has an inlet channel (17A; 17B) for said liquid extending through the plate stack and a separate distribution channel (18A; 18B) also extending through the plate stack. Through first passages (25A; 25B) formed by the heat transfer plates (2A; 2B) the inlet channel (17A; 17B) communicates with the distribution channel (18A; 18B), and through second passages (26A; 26B) also formed by the heat transfer plates (2A; 2B) the distribution channel (18A; 18B) communicates with evaporation flow paths (13A; 13B) defined in alternate plate interspaces between the heat transfer plates (2A; 2B).
