Abstract

The invention provides a composite heat pump air conditioning system based on an environment-friendly low-temperature refrigerant. The composite heat pump air conditioning system comprises a buried pipe heat exchange loop, a refrigerant loop, an air conditioning output terminal, a domestic hot water loop and a heat replenishing unit. The refrigerant loop and the buried pipe heat exchange loop are connected, and the air conditioning output terminal and the refrigerant loop communicate. By means of the arrangement of the domestic hot water loop, low-price domestic hot water can be provided, the underground heat discharge amount can be reduced, and conservation of soil heat near an underground pipeline is kept; and due to the fact that the environment-friendly low-temperature refrigerant is added, energy saving and environmental protection are promoted. Due to the fact that the heat replenishing unit is arranged, richer heat supply modes can be provided, use is more convenient, and the overall air conditioning system is more stable.

Description

technical field [0001] The invention belongs to the technical field of heat pump air conditioners, and in particular relates to a composite heat pump air conditioner system based on an environmentally friendly low-temperature refrigerant. Background technique [0002] The heat pump air conditioner uses the solar energy resources stored in the surface soil and water body as a cold and heat source, no combustion, no smoke exhaust, no waste, no pollution, it is a clean and environmentally friendly technology that utilizes renewable resources. Among them, the ground-source heat pump central air-conditioning system is a heating and air-conditioning system composed of a water-source heat pump unit, a geothermal energy exchange system, and a building system, which uses rock and soil, groundwater or surface water as low-temperature heat sources. Its working principle is: in winter, the heat pump unit absorbs heat from the ground source (shallow water body or rock and soil body) to h...
