Embodiment Construction

[0007] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0008] 1-15 switch 16 direct cooling heat exchanger 17 hot water preparation heat exchanger

[0009] 18 Hot water pool 19 Indoor heat exchanger 20 Floor heating coil

[0010] 21 Heat pump unit 22 Buried pipe heat exchanger 23 Circulating pump

[0011] see figure 1 Underground pipe heating and air-conditioning system and its application. When cooling in summer, the switches 7, 8, 9, 10, 14, and 15 in the system are in the open position, and the switches 1, 2, 3, 4, 5, 6, and 12 are in the open position. , 13 is in the closed state, the U-shaped tube of the buried tube heat exchanger 22 is buried underground, and the circulating working medium in the tube passes through the circulating pump 23 and the switch 9 to transfer the ground temperature of about 15°C underground to the heat pump unit 21 by the circulating working medium The condensing exchanger, after abs...

Abstract

This invention relates to a imbedded tube heating air-conditioning system and its usage composed of heat pump set hot water preparation heat-exchanger direct cooling heat-exchanger, hot water reservoir floor heating coiled pipe, indoor heat exchanger, indoor imbedded tube heat exchanger connected by connectors. The underground part of imbedded tube exchanger is in U-shape structure, the ground part is connected with heat pump set and the direct cooling heat exchanger, forming independent closed circulation pipes filled with circulation working substance and mounted with circulation pump and tube switch. Energy can be transferred to heat pump, hot water preparation heat exchanger direct cooling exchanger, and hot water reservoir.

Description

Technical field: [0001] The invention relates to a heating and air-conditioning system, in particular to an underground pipe heating and air-conditioning system and its application. Background technique: [0002] With the development of science and technology and the continuous improvement of people's living standards, people's requirements for environmental comfort are getting higher and higher, and the energy consumption required for heating and cooling accounts for an increasing proportion of the total energy consumption. Due to the increase in fuel consumption, the environmental pollution on a global scale has been aggravated. It is an inevitable choice to use energy sources such as solar energy and geothermal energy reasonably now. For example, the patent application published on December 29, 1999 with the application number of 99112104. Heating and cooling dual-purpose system of underground energy. This heating and cooling dual-purpose system can only be applied in a...
