SOLAR HEATING AND CENTRAL AIR CONDITIONING WITH HEAT RECOVERY SYSTEM

摘要

The present invention discloses a solar heating and cooling central air-conditioning with a heat recovery system. The system includes a solar heating subsystem for providing supplementary energy to a heat pump, a buffer water tank for storing and minimizing energy loss, a domestic water heater for recovering unused heat, and an air handler ventilation and exchanger subsystem. All parts of the system are connected by antifreeze circulation pipes. The present invention combines the solar technology with the heat pump technology, making it work in extreme cold climate. The system is high energy efficient, versatile, safe, reliable, intelligent and flexible in installation.

主权项

1. A heat pump heating and cooling system for working in a heating or cooling mode comprising:
a first heat transfer medium; a heat pump control subsystem comprising a compressor, an evaporator, a condenser and an expansion valve, containing the first heat transfer medium therein and adapted to operate in a heating or cooling mode; a first heat exchanger connected to a buffer water tank for transferring heat between the first heat transfer medium contained in the heat pump control subsystem and a second heat transfer medium contained in the buffer water tank; a second heat exchanger connected to a solar heat subsystem and adapted for providing supplementary heat to said heat pump control subsystem in the heating mode; and a third heat exchanger connected to a domestic water heater and adapted for transferring heat produced from the said heat pump control subsystem to the domestic water heater; whereby said buffer water tank containing an inlet and an outlet adapted to connect to one or more fan coil units carrying a flow of the second heat transfer medium for heat delivery.
