Abstract
This paper presents a control system for heat pumps. As we know buildings like hotel requires a large amount of heat pumps to generate enough hot water to all the rooms. To assist the workers in monitoring the operation and performance of heat pump, a control system is proposed. The objectives of this project are to design a controller that can control different types of heat pumps and also to monitor the performance and operation of heat pump. Another objective of this project is to analyze time needed for the heat pump to increase the water temperature to a set point temperature using the controller developed and analyze the high and low pressure of the system during operation for safety and performance purpose. The scope of project is to design ladder diagram using Programmable Logic Controller (PLC) that can run the operation of heat pumps and indicate errors of heat pumps. Besides that hardware will be presented to demonstrate the operation. Programmable Logic Controller (PLC) software named as WindLDR, software that is made by IDEC will be used to design the program that operates the flow of heat pumps and errors indication. PLC hardware, IDEC’s FC5A series Micro Programmable Logic Controller will be connected to a LCD display, HG3G series LCD display to monitor the operation and LED lamp to indicate the devices of heat pump that is operating and errors that occur in the system. The experiment is to analyze the discharge pressure, suction pressure of the compressor and also the water tank temperature. With these data recorded through the controller, the performance of the heat pump can be determine. Limits have been set for the pressure and temperature so that the heat pump operation will be terminate when the readings exceed the limit set. To conclude, the controller is able to monitor can control the operation of heat pump.
