Hot gas defrosting insulation board device for cold storage air cooler

Abstract

The invention discloses a hot gas defrosting insulation board device for a cold storage air cooler. The hot gas defrosting insulation board device comprises the old storage air cooler (100), the centers of the front side and the rear side of the cold storage air cooler are provided with a round air inlet (101) and an air outlet correspondingly, wherein the air inlet (101) communicates with the environment outside a cold storage where the cold storage air cooler is installed; the air outlet communicates with an inner object storing space of the cold storage where the cold storage air cooler isinstalled; the old storage air cooler (100) is provided with an air cooler front insulation board device and an air cooler rear insulation board device; and the air cooler front insulation board device is used for optionally opening or closing the air inlet (101), and the air cooler rear insulation board device is used for optionally opening or closing the air outlet. The hot gas defrosting insulation board device is scientific in structural design, the situation that at present, a defrosting zone of an air cooler coil pipe is connected with the low temperature environment in the cold storage,and a low temperature field of the cold storage is influenced is avoided, hot gas is stopped from entering the cold storage, and accordingly, the quality of refrigerated objects in the cold storage is ensured.

Description

technical field [0001] The invention relates to the technical field of hot gas defrosting, in particular to a hot gas defrosting heat insulation board device for a cold storage fan. Background technique [0002] At present, hot gas defrosting is a commonly used defrosting method. The hot gas defrosting system usually includes hot gas pipelines, evaporators, liquid drainage devices, intermediate pressure vessels and low-pressure circulation barrels connected in sequence. The hot gas defrosting method used is : The hot gas pipeline transports the high-temperature gas to the evaporator to melt the frost on the evaporator. The high-temperature gas exchanges heat with the frost on the evaporator and becomes liquid, and then the liquid is discharged to the middle through the liquid discharge device The pressure is reduced in the pressure vessel, and then the liquid is delivered to the low-pressure circulation barrel through the intermediate pressure vessel. During this process, t...

Problems solved by technology

During this process, the exhaust gas of the compressor directly leads to the evaporator (that is, the evaporating device). Due to the relatively large pressure difference, it is easy to have a large impact on the evaporator coil, and it may even burst when the control is improper. The phenomenon

[0003] In addition, during the defrosting process, hot air is inevitably emitted into the cold storage, directly affecting the low temperature field of the cold storage, and causing an increase in energy consumption for defrosting

At the same time, due to this reason, the defrosting process has a great impact on the quality of the stored materials in the cold storage
