Heat recovery evaporative cooling chiller with air-water two-way contact

Abstract

The invention discloses a gas-water double-travel contact heat recycling type evaporative cooling water chiller unit. The gas-water double-travel contact heat recycling type evaporative cooling water chiller unit comprises a unit shell. A double-travel multi-stage direct evaporative cooler is arranged in the unit shell. An exhaust air duct and a fresh air duct are vertically arranged on the left side of the double-travel multi-stage direct evaporative cooler. An exhaust air duct and a fresh air duct are vertically arranged on the right side of the double-travel multi-stage direct evaporative cooler. Heat pipe heat exchange devices are symmetrically arranged on the left side and the right side of the double-travel multi-stage direct evaporative cooler respectively. The heat pipe condensation end of each heat pipe heat exchange device is located in the corresponding exhaust air duct. The heat pipe evaporation end of each heat pipe heat exchange device is located in the corresponding fresh air duct. The air supply outlets of the double-travel multi-stage direct evaporative cooler are communicated with the exhaust air ducts through two air pipes respectively. The end, close to the side wall of the unit shell, of each exhaust air duct is provided with an exhaust outlet. The end, close to the side wall of the unit shell, of each fresh air duct is provided with an air inlet. According to the gas-water double-travel contact heat recycling type evaporative cooling water chiller unit, pre-cooled air exchanges heat and moisture with spray water in a double-travel mode, heat and moisture exchange efficiency is improved, and the cooling capacity generated through the gas-water double-travel contact heat recycling type evaporative cooling water chiller unit is fully used.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to a heat recovery type evaporative cooling chiller with air-water double-pass contact. Background technique [0002] At present, most of the structural forms of evaporative cooling high-temperature chillers are to install spray water in the packing section, so that the spray water and air perform one-way heat and moisture exchange. This structural form is not only insufficient for heat exchange, but also the exhaust air is directly discharged to In the atmosphere, energy will be wasted. The heat pipe is used to recover the cooling capacity of the exhaust air, and the outdoor fresh air is pre-cooled. The pre-cooled air and the spray water perform two-way heat and moisture exchange, which improves the heat and moisture exchange efficiency and can obtain a lower outlet water temperature.
