Flow monitoring device for air energy heat pump

Abstract

The invention discloses a flow monitoring device for an air energy heat pump, and relates to the technical field of energy-saving heat pumps. The flow monitoring device comprises a conveying connecting pipe, a pressure regulating pipe and an electromagnetic monitoring sleeve, wherein a conveying screw is arranged in the conveying connecting pipe, a spiral keel and a conveying disc are installed on the peripheral side face of the conveying screw, and a permanent magnet bolt is arranged on the surface of the conveying disc, and is matched with a magnetic guide bolt in the electromagnetic monitoring sleeve, the conveying disc is arranged, air flow impacts a vortex plate on the surface of the conveying disc to enable the vortex plate to rotate, on one hand, the air flow can be conveyed to the next stage through an air hole and a spiral keel, and on the other hand, the rotating conveying disc drives the magnetic guide bolt to rotate, and magnetic force signals are converted into electric signals. A timing instrument is used for recording the circulating time of the fixed flux, the flow of fluid in the pipe can be monitored, and the flow speed of internal air flow can be monitored in real time; and then the flow monitoring device is matched with a subsequent pressure regulating pipe and a pressure indicating pipe to measure and calculate the pressure of fluid in the pipe, so that multiple monitoring work of flow, flow velocity and pressure in the heat pump pipe is realized.

Description

technical field [0001] The invention belongs to the technical field of energy-saving heat pumps, and in particular relates to a flow monitoring device for air energy heat pumps. Background technique [0002] Air energy heat pump is a low-grade thermal energy resource formed by using the solar energy and geothermal energy of the shallow air on the earth's surface. It adopts the principle of heat pump and realizes the transfer of low-level thermal energy to high-level thermal energy through a small amount of high-level electric energy input. It is also based on Therefore, in recent years, air energy heat pump technology has been widely used in the field of heating; [0003] In order to make reasonable use of air energy, it is necessary to monitor and control the flow rate during daily use of air source heat pumps; especially when the heat load fluctuates, it is necessary to monitor the flow rate of the heat source to avoid heat loss; the existing flow rate The monitoring devi...
