Temperature descaling heat exchanger combination and ground source heat pump system thereof

Abstract

The invention provides a temperature descaling heat exchanger combination and a ground source heat pump system thereof. A first valve and a third valve are opened, and a second valve and a fourth valve are closed, so that hot water enters a second heat exchanger for heat exchange and does not enter a first heat exchanger, a pipe bundle in a second heat pipe vibrates, and therefore the purposes of heat transfer enhancement and descaling are achieved. When the temperature detected by a temperature sensing element in the second heat pipe is higher than a certain value, a controller controls the second valve and the fourth valve to be opened and the first valve and the third valve to be closed, so that the hot water enters the first heat exchanger for heat exchange and does not enter the second heat exchanger, a pipe bundle in a first heat pipe vibrates, and therefore the purposes of heat transfer enhancement and descaling are achieved. Through the temperature detected by the temperature sensing element, the heat exchangers continuously vibrate to remove scale and exchange heat 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] 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, which leads to 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. [0003] Ground source heat pump uses ground source energy soil, groundwater, surface...
