Composite cold supply system based on water cold storage and dew point indirect evaporative cooling water chilling unit

Abstract

The invention discloses a composite cold supply system based on water cold storage and a dew point indirect evaporative cooling water chilling unit. The composite cold supply system comprises the dew point indirect evaporative cooling water chilling unit. The dew point indirect evaporative cooling water chilling unit is connected with a water cold storage tank through a water supply pipe and a water return pipe. The water supply pipe is sequentially connected with a water separator and a water collector through a water separation main pipe communicating with the water supply pipe. The water collector communicates with the water return pipe through a water collection main pipe. According to the composite cold supply system, a dew point indirect evaporative cooling technology and a water cold storage technology are adopted, and according to the characteristic of the large diurnal temperature variation of the northwest dry region, the COP value of the dew point indirect evaporative cooling water chilling unit is increased; by means of a two-side air inlet symmetry structure, the floor space is saved, the air inlet amount is larger, and the heat exchange efficiency is higher; and meanwhile, according to the composite cold supply system, the water chilling unit operates at night through the peak and valley electric charge difference, the aims of peak shifting and valley filling are achieved, the initial investment and operating cost are reduced, system stability is improved, and high practical value is achieved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a composite cooling system based on water storage and dew point indirect evaporative cooling chillers. Background technique [0002] Nowadays, under the national strategy of energy conservation and emission reduction, people pay more and more attention to the utilization of renewable energy, such as the utilization of solar energy, wind energy, water energy and dry air energy. The temperature difference between day and night is large in the dry area of ​​Northwest my country. The high-quality night dry air energy produced by this climate characteristic is fully utilized to store cold at night through the air-conditioning refrigeration system and provide cooling during the day, so as to achieve the purpose of shifting peaks and filling valleys. In line with the poor system, through energy saving and consumption reduction, rational use of electric ener...
