Background
The heat source tower heat pump system is an energy-saving device capable of utilizing high potential energy to enable heat to flow from a low-level heat source to a high-level heat source. The working principle is that the heat source tower extracts heat from air in winter, the extracted heat is transferred to the heat source tower heat pump unit through the liquid secondary refrigerant to be used as a low-temperature heat source, and the heat source tower heat pump heats through the reverse Carnot cycle; in summer, the heat source tower is converted into a water chilling unit, and serves as a high-efficiency cooling tower, and heat is discharged into the atmosphere through evaporative cooling to realize refrigeration.
Currently, heat source tower heat pump systems are widely used as winter heating sources in summer and winter cold areas in China, and the solution amount is reduced due to the fact that the solution of the heat source tower heat pump systems is evaporated in the operation process, so that regular water supplementing is needed. When the temperature of the solution in the heat source tower system is lower than 0 ℃ in operation, water in a pipeline at the joint of the water supplementing pipeline and the solution pipeline can freeze in a static state, and water cannot be normally supplemented when water is required to be supplemented again after the water is frozen, so that the normal operation of the heat source tower heat pump system can be influenced. The traditional solution is that a heat insulation layer is added on a water supplementing pipeline to wind a heat tracing band, the effect is poor when the freezing point of the solution is lower than 0 ℃ and the caliber of the water supplementing pipeline is larger, and the problem that the water supplementing system cannot work normally sometimes needs manual maintenance, so that the labor cost is high; and a large amount of heat tracing bands can also cause electric energy waste after long-term work.
