Tail end cold and heat quantity balancing and redistributing power-saving control method in central air-conditioning monitoring system

Abstract

The invention relates to a tail end cold and heat quantity balancing and redistributing power-saving control method in a central air-conditioning monitoring system and is designed for solving the technical problem that cold and heat quantity balancing and redistributing power-saving management of a tail end branch of a water distributor in the central air-conditioning monitoring system is inconvenient. The key point of the system is as follows: a heat supply portion of the control method comprises a steam boiler, a hot water pump, a plate type heat exchanger and electromagnetic valves; the hot water pump is connected to the plate type heat exchanger and a water collector through a pipeline, winter air conditioning hot water supply of the air-conditioning refrigerating system is connected to the water distributor through a pipeline, the steam boiler is connected to the plate type heat exchange through a pipeline, the electromagnetic valves are separately arranged on branch general pipes of the plate type heat exchanger, the plate type heat exchanger is connected to the water distributor, the branches of the pipeline are separately provided with temperature sensors, and the water outlet of the plate type heat exchanger is connected to a condensate water recovery pond through a pipeline, and moreover, energy conservation optimization is performed on the tail end of the cold quantity by combining a multi-regional cold quantity balanced distribution energy control technology and cold quantity fuzzy pre-judgment energy-saving control technology.

Description

technical field [0001] The invention relates to a central air-conditioning monitoring system, and relates to a control method for end cooling and heat balance and redistribution and power saving in the central air-conditioning monitoring system. Background technique [0002] The central air-conditioning system is composed of one or more cold and heat source systems and multiple air-conditioning systems. Generally, the principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air-conditioning system to offset the heat load of the indoor environment; the heating system is The air conditioning system provides the heat needed to counteract the cooling load of the indoor environment. The refrigeration system is a crucial part of the central air-conditioning system, and its type, operation mode, and structural form directly affect the economy, efficiency, and rationality of the central air-conditioning system in operation. In order to...
