Abstract

The invention discloses an evaporative cooling and air-cooled heat pump type composite water chiller-heater unit, comprising an evaporative water chilling unit, an air-cooled heat pump water chiller-heater unit and a direct evaporative cooler which are connected and combined through a pipe network, wherein the evaporative water chilling unit comprises a high-temperature chilled water air cooler, a low-temperature chilled water air cooler and direct evaporative coolers; the high-temperature chilled water air cooler and the low-temperature chilled water air cooler are connected in parallel; the air-cooled heat pump water chiller-heater unit consists of a condenser, an evaporator and a compressor forming a closed loop; the location of the air-cooled heat pump water chiller-heater unit is arranged to lead the let-in air at one position of the air-cooled heat pump water chiller-heater unit to be from the discharged air of the evaporative water chilling unit, and three direct evaporative coolers are respectively arranged at other three air-inlet surfaces. For the composite water chiller-heater unit provided by the invention, the high-temperature chilled water produced through the evaporative water chilling unit and the low-temperature chilled water produced through the air-cooled heat pump water chiller-heater unit are mixed according to a certain proportion for cooling for users in summer, and the air-cooled heat pump water chiller-heater unit is singly opened for heating for the user during the operation in winter, thereby having obvious energy-saving effect.

Description

Technical field [0001] The invention belongs to the technical field of air conditioning and refrigeration, and specifically relates to a composite cold and hot water unit composed of an evaporative chiller, an air-cooled heat pump cold and hot water unit and a direct evaporative cooler. Background technique [0002] Evaporative cooling air-conditioning technology is an environmentally friendly, efficient and economical cooling method that uses the difference between the dry bulb temperature and the dew point temperature of the renewable energy dry air in the natural environment to obtain cold energy through the heat and moisture exchange between water and air. The characteristics of low cooling equipment cost, ability to significantly reduce electricity consumption and the requirements for electricity during peak electricity consumption, and reduction of greenhouse gas and CFC emissions are known as "zero-cost refrigeration technology", "green air conditioning" and " "Bionic air ...
