基于PLC的小型地源热泵控制系统设计与应用

摘要

Aiming at the shortage of energy and environmental problems, the method of using solar energy and ground source heat pump for heating and cooling is put forward. In this paper, the ground source heat pump working principle is studies. Then,according to the working characteristic of the ground source heat pump, put forward overall control scheme of a ground source heat pump heating system. At the same time, we add switches and use TCP / IP protocol to remote monitoring.Through continuous field testing of the system, it can be concluded that the ground source heat pump control system has the advantages of less pollution, high energy conversion rate and better performance than the traditional boiler and air conditioning.%针对能源紧缺与环境问题,提出以太阳能和地源热泵联合供热制冷的方法.本文通过研究地源热泵机组工作原理,地源热泵各部分工作特点,提出地源热泵供热系统整体控制方案,同时加入交换机,利用TCP/IP协议进行远程监控.通过对系统进行连续实地测试,可以得出地源热泵控制系统和传统的锅炉、空调相比,具有污染小、能源转化率高、性能更好的优点.
