Conventional air-conditioning operating condition distributed phase change energy storage air conditioning system

Abstract

A conventional air-conditioning operating condition distributed phase change energy storage air conditioning system comprises a cooling system, an air treatment and regulation system, a distributed phase change energy storage device, an automatic control device used for controlling and coordinating the systems and pipelines connected to the automatic control device. The conventional air-conditioning operating condition distributed phase change energy storage air conditioning system is characterized in that the conventional air-conditioning operating condition distributed phase change energy storage device is arranged. Since the phase change energy storage device can be embedded seamlessly whenever and wherever, the fatal defect that a chilled water storage system is large in occupation space and cannot be popularized is overcome, the problems that an ice storage system is low in energy efficiency ratio of a main cooling unit and heat exchanging efficiency is low due to multiple heat exchanges are solved, the load of the air conditioning system can be regulated whenever and wherever, and the main cooling unit can be under an optimal operating condition constantly; if combining a peak and valley electricity price policy, the main cooling unit can be operated in the valley electricity price period annually, the power cost of the conventional air-conditioning operating condition distributed phase change energy storage air conditioning system can be comprehensively saved by 50% around as compared with that of a conventional air conditioning system.

Description

technical field [0001] The invention relates to an air-conditioning system, in particular to a distributed energy storage air-conditioning system under conventional air-conditioning conditions. Background technique [0002] Energy plays an important role in the development of human society, and its development and utilization is the driving force for the development of human society. With the development of science and technology, human demand for energy is increasing, and my country's energy consumption is also showing a high growth trend. In the proportion of energy consumption, building energy consumption occupies a relatively large proportion. Building energy consumption has a great relationship with people's living conditions. With the improvement of people's living standards, building energy consumption will be the main growth point of my country's future energy consumption. According to forecasts, my country's final building energy consumption will reach 35% of the cou...

Problems solved by technology

[0003] The most typical solution to the problems mentioned above is to carry out frequency conversion energy-saving transformation on the air conditioning system. The direct superficial beneficial effect is to reduce the power consumption of the freezing and cooling water system, but at the same time it brings a lot of negative effects to the entire air conditioning system. First, it has a certain impact on the energy efficiency ratio of the refrigeration host. Because the frequency conversion transformation reduces the flow of freezing and cooling water, It will directly lead to a decline in the energy efficiency ratio of the main engine, which will increase the power consumption of the refrigeration main engine. After the increase and decrease of power consumption offset each other, the final power saving space is not high; The reduction will lead to insufficient water flow at the end of the air conditioner in some high-rise buildings, so that normal cooling cannot be performed, and cooling failures are likely to occur
