<p>A heat pump system by using water as energy source, includes an energy-collecting equipment, a second heat exchanger, an energy-exalting equipment, a first heat exchanger and a radiator connected in series. The energy-collecting equipment includes a circuit of a low-grade heat exchanger coil, a collector well and a diving pump inside the well in series. The energy-exalting equipment includes a circuit of an evaporation, two compressors, a condenser and a expansion valve in series, the said two compressors are connected in parallel. The radiator includes a circuit of an energy-inputting coil, a pump and several radiation fin in series. Inside the first and second heat exchanger, there is antifreeze. The system has a simple structure, which is easily to install and maintain, and can supply heat or cold to users normally in any case.</p> |
