The circulating pipeline of the system generally adopts a PPR hot water circulating pipe and pipe fittings thereof, and is safe, sanitary and convenient to install. The outdoor pipeline adopts heat preservation measures, and the indoor pipeline can not be heat preserved, but needs to avoid the aging phenomenon of ultraviolet irradiation caused by direct sunlight.
The concrete working process of anti-freezing and anti-overheating solar heat pump coupling heat supply system is as follows:
a heat collection circulation stage: when the temperature of the water outlet of the solar thermal collector reaches a set temperature (generally 45-60 ℃ and is adjustable), the controller drives the thermal collection circulating pump to operate, water in the thermal storage water tank is driven into the solar thermal collector and is heated by the solar thermal collector and then returns to the thermal storage water tank along the thermal collection circulating pipeline through the water outlet of the solar thermal collector, and when the temperature of the water outlet of the solar thermal collector is lower than 50 ℃ (adjustable), the thermal collection circulating pump stops operating, and the water in the solar thermal collector flows back to the thermal storage water tank by natural gravity. In the process, the solar heat collector can be prevented from frost cracking in winter when being overcooled.
A heating cycle stage: when the return water temperature at the heating tail end is lower than the set temperature (generally 40-50 ℃, adjustable), the controller drives the heating circulating pump to operate, and water in the heat storage water tank is directly circulated to the heating tail end (a fan coil or a floor heating coil); and controlling the operation of the heating circulating pump, and when the indoor temperature is lower than a set value (16-22 ℃, the indoor temperature is adjustable), operating the heating circulating pump.
And (3) a night operation stage: after the sun weakens at night, the temperature of the water outlet of the solar heat collector can not reach the set temperature, and hot water in the solar heat collector is completely drained back to the heat storage water tank for heating to be used continuously, so that the solar energy is fully utilized, and the purposes of emptying and preventing freezing are achieved. When the temperature of water in the hot water storage tank is lower than a set temperature (40-50 ℃ and adjustable) at night, the air source heat pump is started, and water in the hot water storage tank is added through the micro-channel coil pipe/copper pipe heat exchanger to continuously provide energy for heating.
Spring, summer and autumn overheating treatment: the solar heat collector has large area and more heat because heating is not needed in spring, summer and autumn, and the phase change heat storage balls in the heat storage water tank can absorb a large amount of heat to ensure that the whole system can not be overheated, and can further shield part of the heat collector in a covering mode to keep part of the heat collector to provide domestic hot water. If continuous rainy days occur, domestic hot water can be provided by starting the air source heat pump to heat water in the water tank.
The energy saving of the system is realized as follows:
(1) solar energy is adopted in the daytime, only the circulating pump consumes electricity, and hot water in the solar heat collector and the circulating pipeline flows back to the heat storage water tank for continuous use at night, so that the solar energy utilization rate is increased;
(2) the phase change heat storage ball in the heat storage water tank can store more heat, so that solar energy can be utilized to a greater extent when the sun is sufficient, and the running time of the air source heat pump is reduced;
(3) the air source heat pump operates at night, peak-valley electricity can be fully utilized for adjustment, and operating cost is reduced.
