Summary of the invention
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and provide a kind of and ensureing to meet on the basis of indoor refrigeration duty demand, make full use of natural cold source, reduce double; two low-temperature receiver radiation refrigeration system of air conditioning energy consumption and operating cost largely.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of double; two low-temperature receiver radiation refrigeration system, driving pump including the water flowing in the first refrigeration mechanism, the radiant coil being connected with the first refrigeration mechanism and driving radiant coil, also include the second refrigeration mechanism, the second described refrigeration mechanism includes cooling tower, heat exchanger and the circulating pump for being circulated between cooling tower and heat exchanger by cooling water, and described radiant coil is also connected with heat exchanger.
Described heat exchanger is dividing wall type heat exchanger.
Connecting line between described radiant coil and the first refrigeration mechanism and heat exchanger is respectively equipped with the first cooling and controls valve and the second cooling control valve.
Connecting line between described cooling tower and heat exchanger is provided with cooling water circulation control valve.
The described water outlet driving pump to be arranged on radiant coil.
The first described refrigeration mechanism is refrigeration unit.
