Air-cooled chiller

Abstract

The invention relates to an air-cooled chiller which comprises a blower fan and a heat radiation chamber. The blower fan is fixed on a support. An air inlet of the blower fan is connected with a centrifugal drier through a pipeline. An air outlet of the blower fan is connected with the heat radiation chamber through a bend pipe. The right end of the heat radiation chamber is provided with a ventilating opening. Radiator coil tubes are disposed inside the heat radiation chamber. Outer walls of the radiator coil tubes are provided with radiating fins. Water inlets and water outlets of the radiator coil tubes are respectively disposed on the outer wall of the heat radiation chamber. The bottom of the heat radiation chamber is equipped with a condensed water outlet. The air-cooled chiller provided by the invention has a simple structure. As the radiator coil tubes are mounted inside the heat radiation chamber, heat inside the radiator coil tubes is dissipated out through the radiating fins and is discharged out of the ventilating opening by the blower fan. The air-cooled chiller has a good water-cooling effect. In addition, a temperature sensor can be arranged in circulating water. Wind speed of the blower fan is controlled through an automatic control system so as to achieve intelligent control of the circulating water temperature. Thus, the water-cooling effect is optimized, water resource is effectively saved, and energy consumption is minimized.

Description

technical field [0001] The invention relates to an air-cooled chiller. Background technique [0002] At present, the production of polyester chips in the petrochemical and textile industries often requires water cooling. In order to save water, recycling is often used. If the circulating water does not dissipate heat in time, the water temperature will become higher and higher, which will affect the cooling effect; at the same time, polyester chips are often dried with a centrifugal dryer. When the centrifugal dryer is working, a fan continuously draws air from one side, and at the same time, the water vapor containing a large number of small water droplets is discharged into the atmosphere, which brings a lot of energy consumption and loses a lot of process water. Moreover, the traditional cooling method is to continuously inject cold water into the circulating water, but this method still causes a lot of waste of process water.
