    Abstract: To provide a refrigeration apparatus that suppresses noise that occurs when reverting to a heating operation and with which it is easy to ensure heating capacity. An air conditioner (1) that is a refrigeration apparatus has, in a refrigerant circuit (10), a compressor (11), an outdoor heat exchanger (13) that functions as an evaporator in a heating operation, an indoor heat exchanger (16) that functions as a condenser in the heating operation, and a four way valve (12). The refrigerant circuit (10) is configured in such a way that a high-pressure value of the refrigerant circuit (10) in a defrost operation is lower than a high-pressure value of the refrigerant circuit (10) in the heating operation. An end-of-defrost frequency decrease rate, which is a rate of decrease in the operating frequency of the compressor (11) in the defrost operation, is set faster than a normal frequency decrease rate, which is a rate of decrease in the operating frequency of the compressor (11) in the heating operation.

    Abstract: The present invention further discloses a method for measuring a degree of superheat of return air of a VRF air conditioning system. The VRF air conditioning system includes: a re-cooling circuit constituted of a first heat exchanger and a second heat exchanger, and a first temperature sensor, a second temperature sensor and a third temperature sensor. The method includes the following steps: obtaining a first temperature value detected by the first temperature sensor, a second temperature value detected by the second temperature sensor, and a third temperature value detected by the third temperature sensor; obtaining a minimum value between the first temperature value and the second temperature value, and a maximum value between the third temperature value and the second temperature value; and calculating a degree of superheat according to the minimum value and the maximum value. The method employs the temperature sensors to achieve accurate measurement of the degree of superheat of the refrigerant at an outlet of the re-cooling circuit, so as to ensure that the refrigerant entering a compressor is not in the liquid form and reduce the cost greatly. The present invention further discloses a VRF air conditioning system.

    Abstract: In an air conditioning system, outdoor units (2a, 2b) and indoor units (3a, 3b) undergo autonomous decentralized control such that the change in respective coolant pressures stays within a prescribed allowable range. If, for example, the temperature setting for the indoor unit (3a) is changed, an outdoor unit such as the outdoor unit (2a) for operating in a pair with the indoor unit (3a) is selected, and the selected outdoor unit (2a) and the indoor unit (3a) having a changed target value are grouped together. Among the grouped indoor unit (3a) and outdoor unit (2a), a control instruction is generated so as to inhibit the change in coolant pressure resulting from the change in temperature setting so as to remain within the prescribed range, and respective control instructions are sent to the corresponding indoor unit (3a) and outdoor unit (2a). As a result, the change in coolant pressure resulting from the change in temperature setting can be kept to the grouped indoor unit (3a) and outdoor unit (2a), allowing the system to be stable. As a result, it is possible to attain a balance between responsiveness and stability in the system.
