Solar-ground source combined heat pump system

Abstract

Disclosed is a solar-ground source combined heat pump system. The solar-ground source combined heat pump system comprises underground heat exchange pipes, a distributor, a check valve, a pump a, electromagnetic valves, a collector heat accumulating device, a pump b, a solar collector, a pump c, a heat pump unit, a safety valve, a buffer heat accumulator, a floor heat supplier, a pump d, a spray head, a heat exchanger, an auxiliary gas heater, a pump e, a fan, a condenser, an evaporator, a water mixing valve and a tap water inlet. The underground heat exchange pipes are buried underground more than 5 meters deep and connected with the distributor through a water pipe; the solar collector is mounted on a roof; the floor heat supplier is mounted under the floor of a room; the collector heat accumulating device, the buffer heat accumulator, the heat exchanger and the auxiliary gas heater are mounted inside the room; all the parts are connected through water pipes, and the water pipes are provided with the electromagnetic valves which are controlled to be open and closed through a controller; the top of the buffer heat accumulator is provided with the safety valve; the heat pump unit is composed of the condenser and the evaporator.

Description

technical field [0001] The invention relates to a combined solar energy-ground source heat pump system, which belongs to the field of energy engineering. Background technique [0002] Energy and the environment are key factors affecting the sustainable development of the national economy. The energy supply situation is directly related to national security and social stability; the energy consumed in the construction field is mainly petrochemical energy such as coal, oil and natural gas. These energy resources are limited and cannot be Regeneration will eventually be exhausted, and traditional energy will cause serious pollution to the environment; China has a large population, and the per capita resource possession is lower than the world average level. Compared with the needs of economic development and people's daily consumption, there is a large gap in energy supply. Moreover, the structure of energy consumption is unreasonable. The energy supply dominated by coal has ca...
