Problems solved by technology

Design according to the winter working conditions, if the ground source heat pump is completely used for heating, the initial investment of the buried pipe and the unit is high, but the efficiency of continuous operation is low, and when the system is running in summer, the capacity of the unit will be too large, resulting in waste
Not only that, because the hea...

Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings, and the present invention is relatively clear to those skilled in the art.

[0010] Referring to the attached figure, this system is connected in parallel with the solar heat collection system and the buried pipe heat collection system, and alternately uses the solar heat supply and the ground source heat pump for heat supply.

[0011] The heat collected by the solar heat collector 1 is stored in the heat storage tank 2. When the sun is directly shining in the daytime and the water temperature in the heat storage tank 2 is high, the valve 3 of the water tank is opened to let the hot water in the water tank pass through the circulating water pump 5 to enter the exchange tank. The heater 7 exchanges heat with the user's system loop to provide floor radiation 8 heating or fan coil 9 heating and cooling requirements; when there is no direct sunlight at night or on cloudy days...

Abstract

The invention relates to a novel geothermal energy solar central air conditioner system and belongs to the technical field of central air conditioning systems, in particular to a high-efficient and energy-saving device for refrigerating or supplying heat for a green environmental protection area. The device comprises a solar thermal collector, a hot water storage tank, a water tank valve, a ground tube valve, a circulating water pump, a ground tube heat collecting system, a heat exchanger, and a floor radiation or fan coil. A ground source heat pump uses energy of normal-temperature soil on shallow ground or ground temperature in water source as a low-grade heat energy resource. The system is suitable for houses and commercial buildings, and is the energy-saving technology with sustainable development. The system realizes heat transmission to ground heat sources by using flowing of a cyclic medium in a closed ground pipe. The system adopts solar energy as auxiliary heat sources. The solar thermal collector is preferentially used for colleting heat when sunshine is sufficient. The heat pump system can be designed with smaller load, and thus, the initial investment of the ground source heat pump can be greatly reduced.

Description

[technical field] [0001] The invention belongs to the technical field of central air-conditioning systems, in particular to a high-efficiency energy-saving device for green and environment-friendly regional refrigeration or heating. [Background technique] [0002] Ground source heat pump is a low-level thermal energy resource that uses the geothermal energy in the shallow normal-temperature soil or water source on the surface. It is suitable for residential and commercial buildings and is a sustainable energy-saving technology. It realizes the heat transfer with the earth heat source through the flow of the circulating medium in the closed buried pipe. In northern China, the system is dominated by heat load. Design according to the winter working conditions, if the ground source heat pump is completely used for heating, the initial investment of the buried pipe and the unit is high, but the efficiency of continuous operation is low, and when the system is running in summer,...
