Abstract: A refrigeration system and refrigeration method for a data center are disclosed. The refrigeration system includes: a first heat exchanger disposed on a back plate of an indoor cabinet of the data center, and a phase-change heat-exchange cooling tower disposed outdoor of the data center. The first heat exchanger and the phase-change heat-exchange cooling tower are communicated by a secondary refrigerant delivery pipeline. The phase-change heat-exchange cooling tower transfers heat carried in the secondary refrigerant into air and condenses the secondary refrigerant to a liquid again; the secondary refrigerant employs a phase-change heat-exchange working medium. An air pump is disposed in the phase-change heat-exchange cooling tower and on a by-pass of the secondary refrigerant delivery pipeline to pressurize the secondary refrigerant in gas-state delivered in the secondary refrigerant delivery pipeline to increase the condensing pressure for condensing the secondary refrigerant to a liquid again.

Abstract: The machine cabinet for dissipating heat includes a housing, and an inner chamber, a liquid working medium accommodating area, a heat exchanger and a delivery passage disposed in the housing. The inner chamber is in a vacuum state and accommodates electronic devices to be cooled; the liquid working medium accommodating area accommodates a liquid working medium, the liquid working medium is converted into a gas working medium to enter the heat exchanger after cooling the electronic devices to be cooled; the heat exchanger liquefies the gas working medium into a liquid working medium and guides the liquid working medium obtained by liquefying the gas working medium into the delivery passage; and the delivery passage is connected with the heat exchanger and the liquid working medium accommodating area and guides the liquid working medium obtained by liquefying the gas working medium into the liquid working medium accommodating area.
