Integrated closed type evaporative cooling-condensation water chilling unit

Abstract

The invention discloses an integrated closed type evaporative cooling-condensation water chilling unit. The unit comprises a packed tower and indirect evaporative cooling sections which are symmetrically arranged on the left side and the right side of the packed tower, two first air inlets are symmetrically formed in the left side and the right side of the packed tower, a second air inlet is formed in one side, far away from the packing tower, of the indirect evaporative cooling section, and a primary air outlet is formed in one side, close to the packed tower, of the indirect evaporative cooling section, a condensation coil pipe is further arranged in the packing tower, the condensation coil pipe is further connected with a mechanical refrigeration unit, the packing tower is connected with a water pipe G5, and the other end of the water pipe G5 is respectively connected with two sets of indirect evaporation cooling sections through two paths, the packing tower supplies water to the tail end of the indoor air conditioner through the water pipe G4, and the water return at the tail end of the indoor air conditioner is divided into two sets of indirect evaporative cooling section water supply through the water pipe G7. The closed type evaporative cooling water chilling unit disclosed has the advantages that the electric energy consumption of mechanical refrigeration can be reduced, the occupied area is saved, and meanwhile, the problems of refrigeration and anti-freezing in winter are solved.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to an integrated closed-type evaporative cooling-condensing chiller. Background technique [0002] Evaporative cooling air-conditioning technology can make full use of dry air energy to produce cold air and cold water to cool down the building interior. In recent years, indoor cooling of some industrial buildings has become a hot spot in the refrigeration and air-conditioning industry, such as textile factories, production workshops, and data centers. In particular, the rapid growth of data center construction has led to more and more various equipment in the computer room to ensure a constant temperature and humidity cooling environment for the data center. The power consumption of the data center will increase greatly, and the cooling system, power distribution system, UPS and generator will increase proportionally, which will bring a major challeng...

Problems solved by technology

However, the temperature of cold water produced by using only indirect-direct evaporative cooling chillers is subject to meteorological conditions. In summer in medium-high humidity areas, or continuous rainy days in dry areas, traditional mechanical refrigeration chillers are still required to produce high-temperature cold water; and When the open-type evaporative cooling chiller is used to produce cold water, when the unit is running, water drift will occur, resulting in water loss, and at the same time, external debris will also enter the cooling water, causing water pollution; at the same time, traditional evaporative cooling Chillers are prone to freezing in severe cold weather in winter, so it is necessary to fully consider antifreeze measures when used in fields such as data centers that require year-round cooling
