  • Heat pump for heat source power recovering secondary solar for subtropical climates
    Patent number: 8919144
    Abstract: A tower heat pump system equipped with a solar energy secondary heat source comprises a cold-heat source tower, a low heat source rotational flow heat pump, a condensate water separator, a supplementary device and a rear end loading system. The tower heating pump system can achieves negative pressure evaporation, cooling and refrigeration in a high-temperature high-humidity condition and efficiently absorb and improve low-temperature-level heat energy from the solar energy secondary heat source in a low-temperature low-humidity condition.
