An air conditioner/heat pump heat storage refrigeration system, comprising:
- an outdoor unit,
- an indoor unit,
- radiation assemblies, and
- an air conditioner/heat pump expansion function box;
- wherein the air conditioner/heat pump expansion function box comprises expansion function box bodies and two distribution pipelines installed in the expansion function box bodies;
- each distribution pipeline in the two distribution pipelines comprises a main path and at least one branch path communicating with the main path, a first end of each main path is provided with an outdoor unit nut head;
- a second end of each main path is provided with an indoor unit nut head;
- an end portion of each branch path is provided with a radiation assembly nut head, one radiation assembly nut head group is formed by all the radiation assembly nut heads of each distribution pipeline, the two outdoor unit nut heads are used for being connected with an inlet and an outlet of the outdoor unit, the two indoor unit nut heads are used for being connected with an inlet and an outlet of the indoor unit, and the two radiation assembly nut head groups are used for being connected with inlets and outlets of radiation assemblies;
- the outdoor unit and the indoor unit are connected into a loop through the air conditioner/heat pump expansion function box, the outdoor unit and the radiation assemblies are connected into a loop through the air conditioner/heat pump expansion function box, and the indoor unit and the radiation assemblies are connected into a loop through the air conditioner/heat pump expansion function box;
- wherein the outdoor unit comprises outer heat exchangers, compressors and a four-way valve connected with the compressors, outlet ends of the outer heat exchangers are connected with a first port of the four-way valve, inlet ends of the outer heat exchangers are connected with one outdoor unit nut head of the air conditioner/heat pump expansion function box, a second port of the four-way valve communicates with outlet ends of the compressors, inlet ends of the compressors are connected with a third port of the four-way valve, and a fourth port of the four-way valve is connected with the other outdoor unit nut head of the air conditioner/heat pump expansion function box;
- the indoor unit comprises inner heat exchangers, inlet ends of the inner heat exchangers are connected with one indoor unit nut head, and outlet ends of the inner heat exchangers are connected with the other indoor unit nut head;
- each distribution pipeline of the air conditioner/heat pump expansion function box comprises one first-level manifold pipe and one second-level manifold pipe, the first-level manifold pipe comprises a first-level main pipe and two first-level branch pipes, the second-level manifold pipe comprises a second-level main pipe and two second-level pipes, the second-level main pipe communicates with one first-level branch pipe in the two first-level branch pipes, the other first-level branch pipe in the two first-level branch pipes is connected with the indoor unit, and the two second-level branch pipes are connected with the radiation assemblies;
- the air conditioner/heat pump expansion function box is further internally provided with a first adjusting pipeline, one end of the first adjusting pipe communicates with the first-level branch pipes of the first-level manifold pipe of the indoor unit nut head of one distribution pipeline, the other end of the first adjusting pipe communicates with one second-level branch pipe of the second-level manifold pipe of the other distribution pipeline, the first adjusting pipeline is provided with a first adjusting stop valve, and the first adjusting stop valve is used for controlling on or off of the first adjusting pipeline in order to change serial and parallel modes of the radiation assemblies and the inner heat exchangers.
