Example Embodiment

[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] The energy-saving control system of the pre-cooler in this embodiment is as follows: figure 1 As shown, including the storage body 1 and the control system, the top of the side wall of the storage body 1 is provided with a cooling fan 2, and the top of the storage body 1 is provided with a cooling exhaust pipe 3, and the storage body 1 is provided with a refrigerant channel, The brine channel and the evaporator, in this embodiment, the evaporator is specifically a plate heat exchanger 7 .

[0021] The refrigerant channel communicates with the first side flow channel of the plate heat exchanger 7 to form a circuit. The parallel compressor unit 4 and the air-cooled condenser 5 are connected in series on the refrigerant channel. The air-cooled condenser 5 and the first side of the plate heat exchanger 7 A throttling element 6 is arranged ...

Abstract

An energy saving control system for a precooling cold store comprises a store body and a control system. An air cooler and a cooling discharge pipe are arranged inside the store body. The energy saving control system is characterized by further comprising a refrigerant passage, a secondary refrigerant passage and an evaporator which are arranged outside the store body, the refrigerant passage is communicated with a first side passage of the evaporator to form a loop, a compressor and a condenser are serially connected to the refrigerant passage, a throttle element is communicated between the condenser and the first side passage, one end of the refrigerant passage is communicated with the condenser through a solution tank, and the other end of the refrigerant passage is communicated with the air cooler and the cooling discharge pipe. Compared with the prior art, the energy saving control system is significant energy saving effect, and energy can be saved by up to 20%.

Description

technical field [0001] The invention relates to a pre-cooler, in particular to an energy-saving control system for the pre-cooler, and belongs to the fields of mechanical refrigeration and storage and processing of agricultural products. Background technique [0002] Pre-cooling refers to the process in which food rapidly drops from the initial temperature (about 25-30°C) to the required refrigeration temperature (0°C-15°C). Pre-cooling is an effective measure to quickly remove field heat, inhibit respiration, maintain the freshness of fruits and vegetables, and extend the storage period. Practice has proved that the temperature of pre-cooled fruits and vegetables is uniform, the breathing intensity is small, and the storage quality can be maintained. However, the current pre-cooling warehouses often do not distinguish between the types and quantities of pre-cooling fruits and vegetables. Regardless of the amount of purchase, all cooling equipment is turned on. The cooling ...
