Automatización de sistema de refrigeración industrial para embarcaciones pesqueras

Abstract

The project aims to automate industrial refrigeration systems for fishing industries and could also be implemented within other industries that use industrial refrigeration processes either for freezing or maintaining processed or to be processed foods. The simulation to be carried out contains elements such as a programmable logic controller (PLC), which will be responsible for establishing the operating ranges of the cooling system. as well as a KTP700 HMI screen, where the working parameters of the cooling system can be displayed, such as such, it will be in conjunction with the indusrial refrigeration system that contains. a refrigerant compressor, a refrigerant liquid receiver, flow valves, solenoid valves. thermostatic expansion valves, pressure transducers, temperature sensor, shell-type heat exchanger tube used as an evaporator, fiber tank used as a container for liquid to cooler, a hydraulic recirculation pump. The implementation process contemplates cooling of the water in a fiber tank simulating the hold of a fishing boat, in such a way that the compressor is turned on, in turn the condenser fans, the water recirculation pump and the solenoid valves together. which will provide an opening for the refrigerant liquid to circulate towards the thermostatic expansion valve, entering the evaporator to achieve heat exchange, in the evaporator the water will be recirculated through the jacket or the external part and the refrigerant inside the tubes, in such a way so that the working pressures of the system and the drop temperature of the water will be monitored up to the parameter established in the PLC.
