Energy saving method and system for climate control system

Abstract

An energy saving system for a climate control system includes zone controllers which poll temperature difference of each heat exchanger downstream of the thermal station, and a system controller which polls degree of opening of all control valves from zone controllers associated with the heat exchangers downstream of the thermal station. Each zone controller configures degree of opening of the valve to regulate the medium flow in response to the temperature difference of the heat exchanger in its respective thermal zone to maintain medium at optimum flow rate to provide a thermal comfort at the thermal zone while being energy efficient. The system controller sends command to the thermal station control system to regulate the outlet temperature of the thermal station to ensure the thermal station consuming the least amount energy to provide the medium to each thermal zone to meet the thermal comfort need at the thermal zones.

Description

technical field [0001] The present invention relates to an environment control system, especially an energy-saving system and method for the environment control system, which not only reduces energy consumption, but also provides a comfortable air-conditioning effect in each air-conditioning control area. Background technique [0002] The environmental control system is especially designed for large buildings that need to adjust the indoor temperature, such as office buildings, hotels, hospitals, high-rise buildings or shopping malls, etc. In order to achieve the most comfortable and energy-efficient goals, the environmental control system must be able to adjust the indoor ambient temperature of different temperature-controlled areas in the same building, so that each temperature-controlled area can provide a comfortable temperature environment. [0003] Traditional environmental control systems generally include a thermal station (Thermal Station), such as a cooling device ...

AI Technical Summary

Problems solved by technology

One is that this system is not able to completely and effectively deliver the correct amount of thermal media flow to each temperature control area, resulting in some temperature control areas may have excessive media flow, or sometimes some temperature control areas may have excessive media flow. low media traffic

Another disadvantage is that the efficiency of heat exchange is low

Due to the unbalanced media delivery in different temperature-controlled areas, this system is inefficient and relatively high in energy consumption.
