Evaporative cooling water chiller and mechanical refrigeration high-temperature water chiller compounded water chiller

Abstract

The invention discloses an evaporative cooling water chiller and mechanical refrigeration high-temperature water chiller compounded water chiller. The water chiller comprises an evaporative cooling water chiller and a mechanical refrigeration high-temperature water chiller which are connected with each other through a pipe network, wherein the evaporative cooling water chiller comprises an air cooler and a direct devaporizer; one side of the air cooler is provided with an air inlet; the direct devaporizer comprises a watertight shutter, a nozzle, fillers and a water tank which are arranged sequentially from top to bottom; an exhaust fan is arranged on the upper part of the direct devaporizer; and the mechanical refrigeration high-temperature water chiller comprises a condenser, a throttle mechanism, an evaporator and a compressor which form a closed loop. During the running of air conditioners, the evaporative cooling water chiller can be run independently under the condition that outdoor air meets requirements to prepare high-temperature chilled water; and when the weather is not suitable for the running of a complete machine, the mechanical refrigeration high-temperature water chiller is used as a sensible heat end to prepare the high-temperature chilled water, and the evaporative cooling water chiller plays the effect of a cooling tower.

Description

technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and in particular relates to a high-temperature chiller composed of an evaporative cooling chiller and a mechanical refrigeration high-temperature water-cooled chiller. Background technique [0002] The water supply temperature at the end of sensible heat is required to be 16-18°C. In dry areas, only evaporative cooling chillers can produce high-temperature cold water that meets the requirements during the entire air-conditioning operation period, without the need for mechanical refrigeration chillers. In areas with medium humidity and high humidity, one of the current methods of producing high-temperature cold water is to use low-temperature cold water (cold water temperature 5-9°C) produced by traditional mechanical refrigeration chillers and high-temperature cold water produced by evaporative cooling chillers. (When the temperature of the cold water is higher than 1...
