背景技术Background technique
水源热泵空调系统，利用地球水所储存的太阳能资源作为冷热源，通过输入少量的高品位电能，实现低温位热能向高位转移，即夏季将建筑物中的热量取出释放到水体中去，冬季则是通过水源热泵主机从河水中提取热量，送到建筑物中去，是一种可再生能源技术。夏季制冷模式，由于河水的温度相对较低，均能满足要求；但是冬季制热模式，当河水温度过低，此时系统制热效果变差，当河水温低于水源热泵系统工作要求的最低温度时，甚至会出现停机等现象，导致系统无法正常运行。The water source heat pump air-conditioning system uses the solar energy resources stored in the earth's water as a cold and heat source. By inputting a small amount of high-grade electric energy, it realizes the transfer of low-level heat energy to high-level, that is, it takes out the heat in the building and releases it to the water body in summer. It is a renewable energy technology that extracts heat from river water through the water source heat pump host and sends it to buildings. In summer cooling mode, the temperature of the river water is relatively low, which can meet the requirements; but in winter heating mode, when the temperature of the river water is too low, the heating effect of the system will become poor. When the temperature is high, there may even be shutdowns and other phenomena, causing the system to fail to operate normally.
