Heating system water loss detection and control method and system

Abstract

The invention relates to a heating system water loss detection and control method and a system adopting the same. The method includes that a check valve is arranged on a unit water return pipe and used for automatically detecting pressure of the water outlet side of a unit water inlet valve or pressure difference between water inlet and water outlet sides, when the pressure of the water outlet side declines obviously or the pressure difference of the two sides increases obviously, the unit water inlet valve is turned off automatically, pressure of a water inlet manifold and a water return manifold is detected automatically, and when pressure in the pipe declines obviously, a main water inlet valve and a main water return valve are turned off; an automatic control valve and a pressure sensor are arranged on the unit water inlet pipe in the system, the check valve is arranged on the unit water return pipe, the water inlet manifold and the water return manifold are provided with respective valves and pressure sensors, the pressure sensor on the unit water inlet pipe is connected with a control unit of the corresponding automatic control valve, and the sensors on the manifolds are connected with a manifold control unit. Water loss of the heating system can be effectively detected and controlled, and the method and the system are adaptable to heating systems of buildings or other places.

Description

technical field [0001] The invention relates to a water loss detection and control method for a heating system and a heating system water loss detection and control system using the method. Background technique [0002] The heating system in existing residences and offices includes a water inlet main pipe for delivering heat medium (hot water or steam) to each heating user and a return water main pipe for the return of heat medium. The unit water inlet pipe and unit return water pipe of the heating unit are respectively The water inlet main pipe and the return water main pipe are connected by pipes. Usually, there are several heating units. For example, there are several water inlet risers and return water risers in a building. Each set of risers is connected in parallel with each floor on the same plane. The user pipelines are connected in parallel, and the different risers are connected in parallel on the same horizontal ring pipe, and the main pipe is connected to each us...
