Heat pipe ground source heat pump system

Abstract

The invention discloses a heat pipe ground-source heat pump system which comprises a ground heat pump unit and an underground heat pipe; an inlet of a compressor in the ground heat pump unit is connected with an outlet of an evaporator, the outlet of the compressor is connected with the inlet of a water-cooled condenser, the outlet of the water-cooled condenser is connected with the inlet of a liquid storage device, the outlet of the liquid storage device is connected with an electromagnetic valve, the inlet of a throttle valve is connected with the outlet of the electromagnetic valve, and the outlet of the throttle valve is connected with the inlet of the evaporator. The underground heat pipe is composed of a group of heat pipes, the group of the heat pipes are vertically arranged in an underground hole, and the upper parts of the group of the heat pipes are connected with the evaporator. Heat pipe media are filled in the group of the heat pipes. The heat pipe ground-source heat pump system of the invention does not need a circulating pump, thereby saving power consumption; working media adopted in the heat pipes can not corrode the underground heat pipe, so the heat pipes can be used for a long time; the underground heat pipe is short, and the flow resistance of a secondary refrigerant is small; as the gas-liquid phase change heat exchange is occurred in the heat pipes, the heat flux density is high.

Description

technical field [0001] The invention relates to a refrigeration air conditioner, in particular to a heat pipe ground source heat pump system. Background technique [0002] Since the reform and opening up, my country's comprehensive national strength and people's living standards have been greatly improved. As one of the basic industries of the national economy, the energy industry has achieved considerable development. However, the development of the energy industry still cannot meet the needs of the rapid development of the national economy and the rapid growth of people's daily energy consumption, and the national energy shortage situation still exists. [0003] To solve the current energy shortage problem, we can start from two aspects: one is to develop renewable energy (such as solar energy, ground source energy, biomass energy, wind energy, etc.), and the other is to save the energy currently used. [0004] Ground source heat pump technology can make full use of grou...

AI Technical Summary

Problems solved by technology

The downside is that groundwater needs to be pumped, which is not allowed in many places

The disadvantage is that it is limited by geographical location, and it can only be used in places close to these water sources
