Problems solved by technology

Because the heat and humidity characteristics of the soil have a great influence on the ground source heat pump system, the thermal characteristics of the soil are mainly related to the parameters such as the solid particle composition, water content (rate) and thermal conductivity of the soil; when the closed-loop ground source heat pump is operating under cooling conditions It may cause the temperature around the bur

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] The enhanced heat exchange device of the underground heat exchanger of the ground source heat pump adopted in the present invention, such as figure 1 The connection diagram of the present invention, the device includes an evaporator 1, a condenser 3, an expansion valve 2, a refrigeration compressor 8, a four-way reversing valve 6, a daily hot water storage tank 7 and a circulating water pump 4. The key of the device is that the underground heat exchanger pipeline 12 is accompanied by a buried pipeline system 13, and at the same time, a soil temperature and humidity sensor 14 is arranged in the soil where the underground heat exchanger pipeline passes, and a water injection pressurized water storage system is added. And the water injection pressurization control circuit 5, wherein the water injection pressurization water storage...

Abstract

This invention discloses a forced heat exchange method and device for underground heat exchanger of earth source heat pump, which contains buried pipe system, soil humidity and temperature sensor, water filling pressuring storage system and control circuit. Said invention is filled water to soil around the underground heat exchanger by detecting the soil temperature and humidity when in summer the detected temperature higher than preset value and humidity lower than preset value, and in winter the detected the soil temperature lower then preset value.

Description
