The water chilling unit is provided with the multiple evaporators, so that the refrigeration effect is improved.
Description
Technical Field
The utility model relates to a cold water machine field, in particular to cold water machine of parallelly connected evaporimeter of many compressors.
Background
The existing water chilling unit adopts a single-shell tubular evaporator, so that the heat exchange effect is poor, and the refrigerating capacity is small.
Disclosure of Invention
In view of the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a water chiller with multiple parallel-connected evaporators, thereby improving the cooling effect.
In order to achieve the above objects and other related objects, the utility model provides a cold water machine of parallelly connected evaporimeter of many compressors, which comprises a housing, be provided with cooling water system in the casing, wherein cooling water system includes evaporimeter, compressor, water pump, condenser, water tank, plate heat exchanger, wherein, the evaporimeter includes two at least, the compressor includes four at least and for the twice of evaporimeter, and all is provided with the income gas port that can with the gaseous state refrigerant heat transfer in every evaporimeter, the water inlet and the delivery port of being connected with the water tank to and the gas outlet that links to each other with the compressor.
Further, the number of the evaporators is two, the number of the compressors is four, and the evaporators and the compressors are arranged in parallel.
Furthermore, the water tank is connected with the evaporator through a pipeline, the pipeline comprises a main pipeline and branch pipelines, the main pipeline is connected with the water tank and is connected with the branch pipelines through a three-way valve, and the branch pipelines are respectively connected with the evaporator.
Further, the compressor is connected with the evaporator through a pipeline.
Further, the evaporator is a shell-and-tube evaporator.
Furthermore, a heat radiation fan is fixedly installed in the inner cavity of the casing, and a cellular network is arranged inside the casing and below the heat radiation fan.
As above, the utility model discloses a cold water machine of parallelly connected evaporimeter of many compressors has following beneficial effect: in this cold water machine, adopt 4 or above compressors, and the tradition adopts 4 segmentation evaporators of single shell pipe length is longer, and area is great, is unsuitable to install, and single shell pipe multistage evaporator refrigerant heat transfer effect is not good, and refrigeration efficiency is low.
Meanwhile, the double parallel evaporators can realize two-to-one connection, and the parallel arrangement can reduce the space area and facilitate refrigeration and heat exchange.
And finally, the water flow of the main pump passes through the parallel double evaporators, so that the cold exchange between the water flow and the low-temperature refrigerant can be completely realized, and the water flow channel is longer than that of a single-shell pipe 4-section evaporation water outlet channel, so that the refrigeration efficiency is increased, and the energy efficiency ratio is enhanced.
