A temperature descaling heat exchanger combination and its ground source heat pump system

Abstract

The invention provides a temperature descaling heat exchanger combination and its ground source heat pump system. The first valve and the third valve are opened, and the second valve and the fourth valve are closed, so that the hot water enters the second heat exchanger for heat exchange. , do not enter the first heat exchanger, so that the tube bundle in the second heat pipe vibrates, so as to achieve the purpose of strengthening heat transfer and descaling; the temperature detected by the temperature sensing element in the second heat pipe is higher than a certain value, and the controller controls The second valve and the fourth valve are opened, and the first valve and the third valve are closed, so that the hot water enters the first heat exchanger for heat exchange, but does not enter the second heat exchanger, so that the tube bundle in the first heat pipe vibrates, thereby To achieve the purpose of strengthening heat transfer and descaling. In the present invention, the temperature detected by the temperature sensing element enables the heat exchanger to continuously vibrate for descaling and heat exchange according to the temperature.

Description

technical field [0001] The invention belongs to the field of heat exchange, in particular to a utilization system of mine ground source heat pumps. Background technique [0002] Since the reform and opening up, my country's comprehensive national strength and people's living standards have been greatly improved. Among them, the gold industry has developed rapidly, people's demand for gold has continued to increase, and the mining depth has continued to increase. high demands. As the mining depth increases, the ground pressure and rock temperature increase, and the difficulties in improving drainage, support, ventilation and other conditions in mines also increase, and the technical difficulties faced will continue to increase. One of the most prominent problems in deep well mining is the deterioration of the underground thermal environment, which not only restricts the safe production and construction of mines, but also threatens the health of miners. [0003] The tradition...

Problems solved by technology

[0003] The traditional method to solve the problem of heat damage in deep mines is mine circulation ventilation, but there are many problems in this method

First of all, as the depth of the mine increases, the shortcomings of its cooling capacity and insufficient ventilation limit become more and more prominent, resulting in a gradual decrease in its cooling effect, making it difficult to meet actual needs

Secondly, the way of circulating ventilation in mines needs to consume a lot of electric energy to drive mechanical equipment to generate forced convection air, and the operation of mechanical equipment will inevitably generate noise, which is uneconomical and affects the working conditions of underground workers
