Problems solved by technology

The purpose of cooling in summer and heating in winter is achieved by switching between 8 cooling and heating switches. However, if one of the valves leaks, it will lead to poor air conditioning effects and increased energy consumption. Once a leak occurs, the troubleshooting process will take a long time and it is difficult to judge The leakage point brings great inconvenience to the operation and management of the ground source heat pump

Abstract

The invention provides an automatic pressure monitoring cold and warm switching valve for a cooling side and a freezing side of a ground source heat pump. The automatic pressure monitoring cold and warm switching valve comprises a monitoring area I, a monitoring area II and a monitoring area III, wherein the monitoring area I, the monitoring area II and the monitoring area III are connected in sequence; and an electric valve I (F1) is arranged between the monitoring area I and the monitoring area II, an electric valve II (F2) is arranged between the monitoring area II and the monitoring area III, a controller is arranged on one side of the monitoring area II, and the controller is connected with and controls the monitoring area I, the monitoring area II and the monitoring area III, the monitoring area I includes a monitoring pipe member, the two ends of the monitoring pipe member are provided with mounting flanges, the upper end of the monitoring pipe member is provided with a pressuretransmitter I (Y1), and one side of the monitoring pipe is provided with a pressure gauge I (D1). According to the automatic pressure monitoring cold and warm switching valve, the valve leakage pointcan be quickly and accurately determined by observing the pressure gauge, and the maintenance time is greatly saved; and all pressure transmitters and electric valves are all automatically controlled, operation is simple and convenient, and one-button operation is achieved.

Description

technical field [0001] The invention relates to the technical field of pipeline monitoring equipment, in particular to an automatic pressure monitoring cooling and heating switching valve on the cooling side and the freezing side of a ground source heat pump. Background technique [0002] The ground source heat pump system is divided into two closed-circuit heat exchange pipelines: the freezing side (indoor side) and the cooling side (ground source side, also known as the heat source side); The side circulation water enters the evaporator of the ground source heat pump host; winter is opposite to summer. Therefore, the ground source heat pump pipeline system needs at least 8 cooling and heating switching valves to switch the waterway. The purpose of cooling in summer and heating in winter is achieved by switching between 8 cooling and heating switches. However, if one of the valves leaks, it will lead to poor air conditioning effects and increased energy consumption. Once a...
