Problems solved by technology

[0002] In related technologies, large cooling capacity chillers generally adopt centrifugal chillers, and centrifugal chillers are prone to surge at low load, so the scope of application is limited
In order to provide cooling capacity, screw chillers generally adopt the form of parallel connection of water systems. The evaporation temperature and condensation temperature of the two systems are exactly the same, so the overall heat transfer effect is poor and the energy efficiency is low, so it needs to be improved.

Abstract

The invention discloses a water chilling unit which comprises a first refrigerant circulating system, a second refrigerant circulating system, a radiating terminal and a cooling tower, wherein when the water chilling unit is in a refrigerating mode, a refrigerating medium passage of a first evaporator, a refrigerating medium passage of a second evaporator and the radiating terminal are sequentially connected end to end by virtue of a first circulating pipeline; a refrigerating medium passage of a first condenser, a refrigerating medium passage of a second condenser and a cooling tower are sequentially connected end to end by virtue of a second circulating pipeline; when the water chilling unit is in a heating mode, the refrigerating medium passage of the first evaporator is connected with an external water source by virtue of a third circulating pipeline; the refrigerating medium passage of the first condenser and the refrigerating medium passage of the second evaporator are sequentially connected end to end by virtue of a fourth circulating pipeline; and the refrigerating medium passage of the second condenser and the radiating terminal are sequentially connected end to end by virtue of a fifth circulating pipeline. According to the water chilling unit disclosed by the invention, the refrigerating capacity and the energy efficiency of the water chilling unit can be improved, and the scope of application of the water chilling unit can be expanded.

Description

technical field [0001] The invention relates to the field of water chillers, in particular to a water chiller. Background technique [0002] In the related art, centrifugal chillers are generally used for high-capacity chillers, and centrifugal chillers are prone to surge when the load is low, so the scope of application is limited. In order to provide cooling capacity, screw chillers generally adopt the form of parallel connection of water systems. The evaporation temperature and condensation temperature of the two systems are exactly the same, so the overall heat transfer effect is poor and energy efficiency is low, so it needs to be improved. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the present invention proposes a water chiller, which has the advantages of large cooling capacity, high energy efficiency and wide application range. [0004] The water ...
