Method for analyzing operation energy efficiency of refrigerating machine room and achieving high efficiency and energy conservation after optimization

Abstract

The invention discloses a method for analyzing the operation energy efficiency of a refrigerating machine room and achieving high efficiency and energy conservation after optimization. The method is characterized by comprising the steps of original design energy efficiency simulation, design of a technical implementation scheme, equipment type selection optimization, pipeline optimization, group control system optimization, machine room mounting construction, machine room equipment debugging, energy efficiency certification and acceptance and operation and maintenance management; the original design energy efficiency simulation comprises the steps that according to the ASHARE standard, the original design energy efficiency of the refrigerating machine room system is simulated, main parameters of equipment are input, Hourly Analysis Program software is used in cooperation for carrying out annual load energy simulation to estimate the cold consumption, and the refrigerating machine room EER is equal to annual accumulated total cold consumption / annual accumulated total electric quantity. The construction process is simple, and the purposes of high efficiency and energy conservation can be effectively achieved after the refrigerating machine room is optimized.

Description

technical field [0001] The invention belongs to the construction field of refrigerating machine rooms in existing buildings, and in particular relates to the energy efficiency analysis of refrigerating machine room operation and a method for achieving high efficiency and energy saving after optimization. Background technique [0002] With the rapid development of the economy, the ownership of commercial building area is increasing day by day, and the energy consumption of the refrigeration machine room in commercial buildings occupies a major part, especially in the high temperature season, the energy consumption is often higher. The concept of high-efficiency computer rooms has been legislated in Singapore and other countries, requiring new buildings to meet certain energy efficiency values. However, most of the refrigeration equipment rooms in China only pay attention to the functional requirements, without considering the operational efficiency, and often fail to meet the...
