NOVEL INTEGRATED COOLING AND REFRIGERATING APPARATUS

WIPO Patent Application WO/2022/116568

A1

An integrated cooling and refrigerating apparatus, comprising a cooling unit, a refrigeration unit, and a control unit. The cooling unit comprises a water pump (6), an air treatment unit (5) and a condenser (2), connected in sequence. The refrigeration unit comprises a compressor (1), a condenser (2), a throttling expansion valve (3) and a fan coil (4), connected in sequence. The cooling unit is connected to the refrigeration unit by means of the condenser (2), and the control unit is electrically connected to the cooling unit and the refrigeration unit respectively. Chilled water from the cooling unit is conveyed to the air treatment unit (5) under the action of the water pump (6) and cools the air, thus achieving first-stage utilization of the chilled water and cooling by the cooling unit, and meanwhile, the chilled water used in the first stage enters the condenser (2), and cools a high-pressure side of the refrigeration unit, thus achieving second-stage utilization of the chilled water and refrigeration by the refrigeration unit, and thus effectively increasing the temperature difference between supply and return water, and implementing large-temperature difference and low-flow chilled water operation, with the energy consumption of transportation being greatly reduced.
