Plate-tube type indirect evaporative cooling and evaporative condensation collaborative coupling water chilling unit

Abstract

The invention relates to a plate-tube type indirect evaporative cooling and evaporative condensation collaborative coupling water chilling unit, which comprises a shell, wherein a packing tower unit is arranged in a middle of the shell; the left and right sides of the packing tower unit are symmetric in structure and the same; the packing tower unit comprises an air inlet arranged on a side wall;the shell in the air inlet is successively provided with an air filter, an evaporative cooling unit, a water baffle a, a direct expansion refrigeration unit, an exhaust fan a and an air outlet a according to an air flowing direction. The collaborative coupling water chilling unit provided by the invention combines the evaporative cooling with direct expansion refrigeration so as to improve the indirect evaporative cooling efficiency effectively, so cold water with a lower temperature is obtained; the condensation temperature and pressure are reduced by using the secondary exhaust with a lowertemperature; and the energy efficiency of the system is improved; the cooling water in an evaporative cooling section and a mechanical cooling section is flexibly configured, so the range of the wateroutlet temperature is widened; and the water chilling unit is energy-saving and high-efficiency.

Description

Technical field [0001] The invention belongs to the technical field of air conditioning equipment, and specifically relates to a plate-tube type indirect evaporative cooling and evaporative condensation cooperatively coupled chiller. Background technique [0002] With the development of social economy, the energy consumption of air-conditioning systems has increased significantly, especially the energy consumption of preparing cold water remains high. Traditional direct expansion refrigeration and air-conditioning in the extreme temperature in summer, because the outdoor environment temperature is too high, the condenser heat dissipation is not smooth, the compressor is overheated to protect, and even cause failure and shutdown. The evaporative cooling technology uses water as the medium to produce cold air or cold water through direct or indirect contact between air and water; evaporative cooling chillers are susceptible to outdoor weather conditions, and the outlet water temper...
