Embodiment 2

[0057] Winter mode 2: Heat storage. In this mode, the air source heat pump 27 stores heat for the heating system, the air source heat pump 27 and the fan 28 are turned on, and the electric butterfly valve 25 and the electric butterfly valve 26 are in In the closed state, the air source heat pump 27 does not directly supply heat to the heating system. The circulating water pump 17 of the heating and cooling system is in a low-speed operation state, and the heat storage, heat storage, cooling, and releasing heat pumps 9, electric butterfly valve N 10, electric butterfly valve A 14, and electric butterfly valve B 15 on the heating and cooling circulation pipeline In the open state, the heating system circulates at a low speed; the cold storage and heat storage pumps 22 on the heat storage system, as well as the electric butterfly valve C20, electric butterfly valve D23, and electric butterfly valve E24 are all in an open state, so that the heat of the air source heat pump 27 passe...

Embodiment 3

[0059] Winter mode 3: heat storage, heat release, and heat supply. In this mode, the heating system is in a state of heat storage and heat release for indoor terminal equipment, and the air source heat pump 27 and fan 28 are turned on. The electric butterfly valve 25 and the electric butterfly valve 26 are in a closed state, and the air source heat pump 27 does not directly supply heat to the heating system. The circulating water pump 17 of the heating and cooling system is in a normal speed state, and the heat storage, heat storage, cooling and releasing heat pumps 9, electric butterfly valve N 10, electric butterfly valve A 14, electric butterfly valve B 15 on the heating and cooling circulation pipeline In the open state, the heating system circulates normally to supply heat to the indoor terminal equipment. The cold storage and heat storage pumps 22 on the heat storage system, as well as the electric butterfly valve C20, electric butterfly valve D23, and electric butterfly...

Embodiment 4

[0061] Winter mode 4: heat release and heat supply. In this mode, the heating system stops heat storage and only releases heat to provide heat for indoor terminal equipment. The air source heat pump 27 and fan 28 are in a closed state, and the electric butterfly valve 25 and all The above-mentioned electric butterfly valve 26 is in the closed state, and the cold storage and heat storage pumps 22 on the heat storage system, as well as the electric butterfly valve C20, the electric butterfly valve D23, and the electric butterfly valve E24 are all in the closed state, and the heat storage is interrupted. The circulating water pump 17 of the heating and cooling system is in a normal speed state, and the heat storage, heat storage, cooling and releasing heat pumps 9, electric butterfly valve N 10, electric butterfly valve A 14, electric butterfly valve B 15 on the heating and cooling circulation pipeline In the open state, the heating system normally circulates to supply heat to the...

Abstract

The invention discloses a cold and heat combined supply system capable of comprehensively utilizing clean energy and production waste heat. The cold and heat combined supply system comprises a heatingand refrigerating water supply and return system, and a domestic hot water supply and return system, wherein the heating and refrigerating water supply and return system is equipped with a cold and heat storage water tank; the cold and heat storage water tank is connected with a cold and heat release heat plate type heat exchanger and a cold and heat storage plate type heat exchanger system as well as an air source heat pump system in parallel; the system, a heating water supply and return pipeline and a refrigerating water supply and return pipeline define a circulating system; and a solenoid valve for controlling on and off is arranged on each circulating pipeline. The domestic hot water supply and return system comprises a heat storage water tank which is in parallel connected with anair compressor energy supply system and a solar energy supply and compression system; and the heat storage water tank, the cold storage water tank and the heat storage water tank are equipped with connecting pipelines, so that on and off are controlled according to the needs. According to the cold and heat combined supply system disclosed by the invention, the systems are matched in a staggered mode, so that operation under different modes can be realized, and therefore, different needs of heating and refrigerating a building in different seasons are met, various clean energy is sufficiently utilized, and energy conservation and consumption reduction are realized.
