Description
Technical Field
The utility model relates to the technical field of heat source tower heat pump air conditioners, in particular to a water supplementing and anti-freezing system for a heat source tower heat pump.
Background
The heat source tower heat pump system realizes heat transfer through direct contact of circulating solution and air, and has two functions of heat absorption and heat release. In summer, the circulating solution is cooling water, and heat is dissipated to the air through evaporation of the cooling water. In winter, the circulating solution is a carrier medium with the freezing point lower than zero, and under the condition of higher relative humidity, heat in a low-temperature environment is extracted through temperature difference or moisture absorption. And under the condition of low relative humidity, except that the temperature difference absorbs heat, the phenomenon of evaporation can occur.
Therefore, heat source tower heat pump systems have a need for water replenishment in both summer and winter. In summer, the environment temperature is higher than zero, and water supplement is free of icing risk. In winter, the circulating low-temperature solution and the environment temperature are both lower than zero, so that the risk of water replenishing and icing exists.

According to the heat source tower heat pump water replenishing and anti-freezing system, when the heat source tower 10 needs to be replenished with water, the second control valve 52 is closed at first, and water leakage from the water outlet in the water replenishing process is avoided. Then, the first control valve 51 is opened, the water source 30 starts to supply water, and water flows into the water replenishing pipeline 20 from the water inlet pipe 31 and enters the heat source tower 10 from the water replenishing pipeline 20 and the water replenishing port 11. When the water injection amount reaches the requirement, the first control valve 51 is closed firstly, and the water supply is stopped; then, the second control valve 52 is opened, and the water remaining in the makeup water pipe 20 flows into the drain pipe 40 from the second end of the makeup water pipe 20 by gravity and is discharged from the drain opening of the drain pipe 40. Through the above operation, the residual water in the water replenishing pipeline 20 can be emptied, and the water pipe is prevented from being frozen and cracked in cold weather.
