[0047] The solar assembly 402 is a solar light and heat assembly, a solar photovoltaic assembly or a solar photovoltaic and light and heat assembly.

[0048] The four-way reversing valve 308 adjusts the direction according to the cooling and heating demand and the first, second, third and fourth set temperature intervals, the first set temperature interval is 23-26℃, the second set temperature interval is 20-24℃, the third set temperature interval is 10-20℃, and the fourth set temperature interval is 35-45℃.

[0049] When the energy-saving system is an open system, the heat pump unit is communicated with the water channel of the water flow window unit 100 through the first water pump 502, the third water pump 504 is arranged in the heat pump, and the heat pump unit outputs water flow meeting the preset temperature to the water flow window unit 100; the water inlet 311 of the first heat preservation energy storage box is communicated with the window outlet 108 of the water flow window unit 100, the water outlet 312 of the first heat preservation energy storage box is communicated with the window inlet 107 of the water flow window unit 100, and the filter 104 is arranged at the window inlet 107 of the water flow window unit 100.

[0050] When the energy-saving system is an open system and the water flow window supplies cooling:

[0051] When the indoor temperature is higher than the first set temperature interval, the first water pump 502 is started, the four-way reversing valve 308 is adjusted so that the first heat exchanger 303 is an evaporator and the second heat exchanger 304 is a condenser, the refrigerant of the heat pump unit absorbs heat from the first heat preservation energy storage box 301 in the first heat exchanger 303 and releases heat into the second heat preservation energy storage box 302 when passing through the second heat exchanger 304, and the refrigerant in the first heat preservation energy storage box 301 is transported to the water flow window unit 100 for radiation cooling through the first water pump 502;

[0052] When the indoor temperature is lower than the first set temperature interval, if the user end 403 has hot water demand, the second heat preservation energy storage box 302 and the solar component 402 jointly supply hot water to the user end 403, and the municipal pipe network 401 supplies water to the second heat preservation energy storage box 302.

[0053] When the energy-saving system is an open system and the water flow window supplies heating:

[0054] When the indoor temperature is lower than the second set temperature interval, the first water pump 502 is started, the four-way reversing valve 308 is adjusted so that the second heat exchanger 304 is an evaporator and the first heat exchanger 303 is a condenser, the refrigerant of the heat pump unit absorbs heat from the second heat preservation energy storage box 302 when passing through the second heat exchanger 304 and releases heat into the first heat preservation energy storage box 301 when passing through the first heat exchanger 303, and the first water pump 502 transports the refrigerant absorbing heat in the first heat preservation energy storage box 301 to the water flow window unit 100 for radiation heating.

[0055] When the indoor temperature is higher than the second set temperature interval, if the temperature of the first heat preservation energy storage tank 301 is lower than the fourth set temperature interval, the auxiliary electric heater 305 in the first heat preservation energy storage tank 301 is started; if the temperature of the first heat preservation energy storage tank 301 is higher than the fourth set temperature interval, the fourth water pump 505 is started to guide the hot water supplied by the solar component 402 to the second heat preservation energy storage tank 302 into the first heat preservation energy storage tank 301.

[0056] The specific principle is that for the open system, in the cooling season, when the indoor temperature is higher than the first set temperature interval, the first water pump 502 is started. By adjusting the four-way reversing valve 308, the first heat exchanger 303 of the heat pump is evaporator, and the second heat exchanger 304 is condenser. The refrigerant evaporates by reducing pressure through the throttle valve, absorbs heat from the first heat preservation energy storage tank 301 in the first heat exchanger 303, and then is compressed by the compressor 306. When passing through the second heat exchanger 304, the heat is released to the second heat preservation energy storage tank 302. The working medium in the first heat preservation energy storage tank 301 is transported to the adaptive radiation window energy-saving system by the circulating first water pump 502 to radiate and supply cooling to the indoor. When the indoor temperature is lower than the first set temperature interval, the rotation speed of the water pump and the circulating water pump is reduced or stopped. In addition, when there is a hot water demand in the building, the second heat preservation energy storage tank 302 and the solar light and heat component or the solar photovoltaic component or the solar photovoltaic and light and heat component jointly supply hot water to the user. At the same time, the second heat preservation energy storage tank 302 is connected by the municipal pipe network 401 to supplement water to the second heat preservation energy storage tank 302.

[0057] The open system can directly use the flowing water of the whole system as the flowing working medium, and the heat exchanger part is omitted. The flowing working medium directly exchanges heat, improves the heat exchange efficiency, and the system structure is simple and the cost is low, which is suitable for occasions with limited engineering cost.

[0058] For the open system, in the heating season, when the indoor temperature is lower than the second set temperature interval, the first water pump 502 is started, the four-way reversing valve 308 is adjusted, the second heat exchanger 304 of the heat pump is evaporator, the first heat exchanger 303 of the heat pump is condenser, the refrigeration working medium is evaporated after pressure reduction through the throttle valve, heat is absorbed from the second heat preservation energy storage tank 302 through the second heat exchanger 304, then the refrigeration working medium steam is compressed through the compressor 306, and heat is released to the first heat preservation energy storage tank 301 when passing through the first heat exchanger 303, finally the hot water in the first heat preservation energy storage tank 301 is transported to the adaptive radiation window energy-saving system to radiate heat to the indoor. When the indoor temperature is higher than the second set temperature interval, the speed of the first water pump 502 is reduced or stopped. When the temperature of the first heat preservation energy storage tank 301 is lower than the fourth set temperature interval, the auxiliary electric heater 305 in the first heat preservation energy storage tank 301 is started; when the temperature of the first heat preservation energy storage tank 301 is higher than the fourth set temperature interval, the valve on the second bypass pipe 310 (the first bypass pipe 309 is provided with the third water pump 504, and the second bypass pipe 310 is provided with the fourth water pump 505) is opened and adjusted, part of the low-temperature hot water generated by the solar light and heat component or the solar photovoltaic and heat component or the solar photovoltaic and heat component is introduced into the first heat preservation energy storage tank 301, until the fourth set temperature interval heating demand is met.
