Embodiment 1

[0031] like Figure 1-6 As shown, the present invention is a modular distributed air source heat pump unit, which includes a heat pump circulation module 1 and an end circulation module 2. The heat pump circulation module 1 and the end circulation module 2 are connected by a closed insulation pipe, and the heat pump cycle Module 1 is responsible for extracting the heat and cold in the atmosphere, and the terminal circulation module 2 is responsible for sending the heat and cold to the end of the user.

[0032] Among them, the heat pump cycle module 1 adopts a modular design and is assembled by two or more standardized heat pump cycle modules 11, and the refrigerant side of the heat pump cycle modules 11 are independent from each other, and the water side is connected in parallel. The heat pump cycle The module 11 is composed of energy side heat exchanger 111, expansion valve 112, compressor 113, four-way valve 114 and air side heat exchanger 115, energy side heat exchanger 111...

Embodiment 2

[0036] Wherein, the terminal circulation module 2 is a distributed circulating water supply mode, and is equipped with a terminal circulation pump 21, a module pump 22, an equalizing tank 23, and the terminal circulating pump 21 forms a terminal water circulation with the equalizing tank 23. The pressure tank 23 forms a heat pump water cycle, and the terminal circulation pump 21, the module pump 22, and the pressure equalization tank 23 adopt a secondary pump system and are connected through the same pipeline.

[0037] Terminal circulation pump 21, module pump 22, pressure equalization tank 23, the cycle sequence of terminal circulation pump 21 is heat pump circulation module 11 return water port → module pump 22 → equal pressure tank 23 → terminal circulation pump 21 water supply port, terminal circulation pump 21 return water port →Equalizing tank 23→Water supply port of heat pump circulation module 11→Water supply port of heat pump circulation module 11.

Abstract

The invention discloses a modular distributed air source heat pump unit. The modular distributed air source heat pump unit comprises a heat pump circulation module set and a tail end circulation module, the heat pump circulation module set and the tail end circulation module are connected through a closed heat preservation pipeline, the heat pump circulation module set is responsible for extracting heat and cold in the atmosphere, the tail end circulation module is responsible for sending heat and cold to a user tail end, the heat pump circulation module set adopts modular design and is formed by assembling two or more standardized heat pump circulation modules, the refrigerant sides of the heat pump circulation modules are mutually independent, the water sides of the heat pump circulation modules are connected in parallel, and each heat pump circulation module is composed of an energy using side heat exchanger, an expansion valve, a compressor, a four-way valve and an air side heat exchanger. According to the unit, air source heat pump circulation modular design is adopted, the heat pump circulation module set and the tail end circulation module are combined according to requirements and fixed in a centralized manner through a steel structure support, the equipment occupied area is reduced, and construction and design site selection are convenient.

Description

technical field [0001] The invention relates to the field of heat pumps, in particular to a modular distributed air source heat pump unit. Background technique [0002] The heat pump unit is a cycle system composed of compressor-condenser-throttle-evaporator-compressor and other devices. The refrigerant circulates in the system under the action of the compressor. It completes the process of increasing the pressure and temperature of the gaseous state in the compressor, and the temperature is as high as 100°C. After entering the condenser, it exchanges heat with the heat dissipation source to release heat. The refrigerant is cooled and converted into a high-pressure liquid state of about 1.5Mpa. When it runs to After the restrictor, the pressure suddenly drops to about 0.4Mpa. When it runs to the evaporator, the liquid state quickly absorbs the heat of the heat-absorbing source and evaporates, and then turns into a gaseous state again. At the same time, the temperature drops...
