The heat-source tower heat pump system has the problem of solution dilution when it operates in winter. A solution regeneration design of heat-source tower based on vacuum boiling and condensation integration is proposed
and experimental tests are constructed. The results show that:with the increase of solution concentration
regeneration efficiency and regeneration rate have the trend of increasing first and then decreasing later
and have the best data at the ethylene glycol concentration of 26%. With the increase of vacuum value
regeneration efficiency and regeneration rate increase greatly
but the reliability of system can be decreased. With the inlet solution temperature of 36℃
and with electric heater outlet valve open time 12 s
regeneration efficiency and regeneration rate can be reached to the best. In the normal time
regeneration efficiency can be higher than 3.40 kg/(kW·h) and regeneration rate can be higher than 550 kg/d. Compared with traditional solution regeneration
