In this embodiment, the condensing unit 2 includes a condenser 21, an energy storage unit for providing cold and/or heat to the condenser 21, and a temperature control unit. Where "providing cold and/or heat" means that cold may be provided, heat may be provided, or both cold and heat may be provided, but the cold and heat are provided under different conditions and not both cold and heat.
The temperature control unit is in communication connection with the energy storage unit and controls the energy storage unit to provide cold or heat for the condenser 21. Those skilled in the art will appreciate that: "providing refrigeration" refers to providing a medium to the condenser that is cooler than it is, for example, by fan driving air that is cooler than the condenser 21; by "providing heat" is meant providing a medium to the condenser 21 that is at a higher temperature than it is, for example by driving air at a higher temperature than the condensing assembly 2 by a fan.
When the condensing temperature of the refrigerating unit 100 is higher than the preset condensing temperature range, the condensing assembly 2 is supplied with cold energy through the energy supply unit; when the condensing temperature of the refrigerating unit 100 is lower than the preset condensing temperature range, the cooling power supply is reduced or stopped by the power supply unit or the heat is supplied to the condensing assembly 2; the condensing temperature is controlled within a preset condensing temperature range, so that the refrigerating unit 100 can normally operate or maintain an optimal operating state under any working condition.

R134a 15℃～80℃ 35℃～60℃
R22 20℃～70℃ 30℃～50℃
R404a 15℃～60℃ 35℃～45℃

The pressure on the refrigeration circuit of this section is almost the same, so the pressure sensor is arranged at any position and the measured result is almost the same; the condensing temperature is then converted from the detected pressure.
In another embodiment, the sensor includes a temperature sensor for measuring the temperature of the refrigerant in the condenser 21, where the temperature sensor is disposed at the second half of the condenser 21, or disposed at the outlet of the condenser 21, or disposed on a refrigeration line connected in series with the condenser 21, for example, a refrigeration line between the outlet of the condenser 21 and the inlet of the throttling element 3, and the temperature of the collected liquid refrigerant is substantially the same as or not different from the condensation temperature, and may be approximately the condensation temperature, or may be empirically calibrated to be the condensation temperature. In general, the condensation process of the refrigerant is completed in the condenser 21, and therefore, it is preferable to provide a temperature sensor at the latter half of the condenser 21 or at the outlet of the condenser 21.

The ambient temperature may be set at any position of the condenser 21 or the refrigerating unit, or may be set on a product using the condensation temperature management system 100. The ambient temperature refers to the temperature of the working environment of the condenser 21, for example, a ring temperature sensor is placed at an air inlet of the air-cooled condenser, and if the detected temperature is higher, the ring temperature is higher, and the air passing through the condenser cannot effectively cool the condenser, so that the condensing temperature is also higher.
