Problems solved by technology

[0004] Taking the air source heat pump as an example, the condensation temperature is 52°C, the outdoor air temperature is -18°C, and the evaporation temperature is -20°C. When the traditional refrigerant R22 is used, the evaporation temperature is -20°C, the evaporation pressure is 0.244Mpa, and the condensation temperature is 52°C. The condensing pressure is 2.03Mpa, the compression ratio reaches 8.3, when the most environmentally friendly R410 refrigerant is used, the evaporation temperature is -20°C, the evaporation pressure is 0.4Mpa, the condensation temperature is 52°C, the condensing pressure is 3.2Mpa, and the compression ratio reaches 8, while the current compressor The highest compression ratio is 7, so the air source heat pump cannot be used in the north
[0005] It can be seen that the energy efficiency ratio of the former equipment is very low, and the latter equipment cannot be used.

Abstract

The invention discloses a geothermal paved heating device comprising a geothermal coiled pipe. The geothermal paved heating device is characterized in that a bonding layer, a leveling layer, a positioning layer and a heat-insulating layer are arranged from top to bottom; the thickness of the bonding layer is 3-15 mm; the geothermal coiled pipe is arranged on the positioning layer; and the coiled pipe pitch of the geothermal coiled pipe is 1.5-4.5 times of the pipe diameter. In the invention, dense pipelines are used and a high heat-conducting material is used for reducing terminal heat resistance in a large area, so that electric charge for heating in the whole winter is equivalent to 30 percent of that of concentrated heating, and the comprehensive expense of the equipment is only equivalent to 50 percent of that of the screen charge of boilers. The geothermal paved thickness is 2 / 3 that of the prior art, so that the floor slab load can be greatly reduced, and meanwhile, the noise interference among floors can be reduced.

Description

technical field [0001] The invention relates to a heating and cooling device, in particular to a high-efficiency and environment-friendly geothermal heating device. Background technique: [0002] Heating in the northern region basically uses coal-fired boilers to deliver hot water to the households. The water temperature is usually 55-80°C. When the water temperature is 60°C, the floor heating heat dissipation is only 70W / m 2 , the radiators designed according to the above water temperature have been used for hundreds of years, and the geothermal pipe cooling system has also been used for decades. Pipeline connection, water source heat pump system energy efficiency ratio is very low, air source heat pump system because the minimum evaporation temperature must be below -20°C, when the condensation temperature is 50°C, no matter what refrigerant is used, the compression ratio is greater than 7, which is far beyond The operating range of the existing compressor is exceeded, ca...
