Abstract

The invention relates to an air condition that uses heat pump and ground as the heat source. It includes heat collection well, heat pump, and heat exchange coil pipe of user. A flow pipe and a return pipe are set in the heat collection well. The top is set a current equalizer, and the bottom is set a current collector. Return room is set on the current equalizer, and water collection room is set under the current collector. Between the current equalizer and the current collector there are cobbles filled in. The heat pump includes the first heat pump, which is made up of the first evaporator, the first compressor, the first condenser, and the first expansion valve; the vaporizing and cooling device is parallel connected in loop of the first evaporator, the first compressor, the first condenser and the first expansion valve; the first evaporator is connected to the heat liberation coil pipe, and the first condenser is connected to the heat exchange coil pipe of user. The device expands the use range of the low grade energy.

Description

technical field [0001] The invention relates to an air-conditioning system using a heat pump for raising low-level energy to high-level energy and using the earth as a heat source. Background technique [0002] When using natural energy for heating, ordinary heat pumps need to increase heat energy for heating purposes, but such heat pumps often have strict requirements for low-level energy collection. For example, in order to achieve the temperature of about 50°C required for heating, the temperature of low-level energy collection is often required to be 15°C. When the temperature of low-level energy collection is lower than 5°C, the system cannot achieve the purpose of heating. The temperature of low-level heat sources with huge reserves in nature, such as the earth, rivers, lakes, and seas, changes with temperature changes, especially in northern regions that need heating, where the temperature of rivers, lakes, and seas is mostly below 5°C. Therefore, ordinary heat pumps ...
