SYSTEM AND METHOD FOR DYNAMIC CONTROL OF AN EVAPORATOR

摘要

The invention relates to a plate heat exchanger including a plate package, which includes a number of first and second heat exchanger plates which are joined to each other and arranged side by side in such a way that first and second plate interspaces are formed. 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.

1. System for dynamic control of the operation of an evaporator, the system comprising an evaporator, a plurality of injector arrangements, a sensor arrangement and a controller, wherein
the evaporator comprises an outlet, a plurality of fluid passages and at least one inlet for the supply of a fluid to the outlet via the plurality of fluid passages during evaporation of the fluid, each injector arrangement comprises at least one injector and at least one valve, and each injector arrangement being arranged to supply a flow of the fluid to at least one of the fluid passages via the at least one inlet of the evaporator, the sensor arrangement is arranged to measure temperature and pressure of the evaporated fluid, or the presence of any liquid content in the evaporated fluid, and the controller is arranged to communicate with the valves of the injector arrangements for the valves to control, based on information received from the sensor arrangement, the amount of fluid to be supplied by each injector arrangement to each fluid passage in the evaporator in order for the evaporator to operate towards a set-point superheating value.
