Document Type and Number:
WIPO Patent Application WO/2004/020916
Kind Code:
A1
Abstract:
The present invention discloses a vacuum terrestrial heat-extracting device and an air-conditioning system with the device. The device includes a closed container in which the upper part is a vacuum chamber and the lower part is a heat-exchanging chamber. A plurality of holes are provided in the side of the heat-exchanging chamber. A heat exchanger is provided in the heat-exchanging chamber, both ends of which extend from top of the vacuum chamber, and the vacuum chamber is connected to a vacuum pump and a suck valve respectively. An air-conditioning system using the device for supplying hot water includes an energy extractor and an air-conditioner, and the energy extractor is comprised of a heating circuit and a heat-exchanging circuit. The heating circuit is formed with an evaporator, a compressor, a condenser and an expansion valve connected by pipelines, and the water side pipe in the heat-exchanging circuit coupled with the condenser is connected to a hot water container by a pipeline. The vacuum terrestrial heat-extracting device is provided with features of following: less occupying area, simple structure, high heat-exchanging efficiency, long working life, easy installation and operation, and less energy wasting. This device can collect the cold and heat energy of low quality stored underground, and then the cold or heat energy extracted by the energy extractor can supply to residence, and provide sanitary hot water.
