The invention relates to a solar-energy-combined cold and warm dual power supply
system and a control method thereof. The solar-energy-combined cold and warm dual power supply
system is characterizedin that the
system comprises a
solar energy heat cycle unit (101), a gas heat cycle unit (201), an absorbed
refrigeration cycle unit (301), an air conditioner cycle unit (401) and a floor
heating cycle unit (501); the start and stop of the
solar energy heat cycle unit and the gas heat cycle unit are switched mutually by controlling the switch of a corresponding electric valve; and the connection
modes of the
solar energy heat cycle unit and the gas heat cycle unit, the air conditioner cycle unit and the floor
heating cycle unit are through the absorbed
refrigeration unit or a heating
water supply pipe (17) or a heating water return
pipe (18), through the operation on an indoor temperature controller (41), a
system controller (40) controls the switch of the corresponding electric valve to select the connection mode, and thus the cooling or heating of a fan coil and the floor heating is achieved. According to the solar-energy-combined cold and warm dual power supply system, the effectiveuse time of the floor heating is prolonged, the load power of the fan coil is further reduced, thus the regulation process of the indoor environment is more energy-saving, and the body feeling is more comfortable.
