Cold storage installation Company: "how to reduce the profit of frozen warehouse? What's the way to control the cost? "The freezer is a unique building for the food industry to refrigerate and freeze, and maintain the necessary bottom temperature. The concrete floor, wall and roof are paved with dehumidification layer and thermal insulation material with the thickness of stainless steel to reduce the external heat input. Together, it is convenient to reduce the radiant heat of absorbing color light. The wall surface of frozen warehouse is usually painted black or light gray Color. Because of the left and right characteristics of the frozen warehouse building, in addition to the strict flame retardant, airtight, adhesive force and cold resistance to ensure the safety of the building in the design scheme and construction engineering construction, it is also necessary to implement the institutionalized management according to the characteristics of the frozen warehouse in the usual application management, so as to ensure the engineering quality, so as to improve the service life of the extended time and the operation period cost It can save the maintenance cost and improve the economic benefits of enterprises.
1、 The heat preservation door should be closed tightly without running cold
The insulation door is the voice of the freezer. It is based on the voice of the staff and workers, goods in and out, and even the exchange of cold and hot acetylene gas. Therefore, the insulation door is the key position of control. The convective heat transfer penetrates into the storage space according to the opening of the translation door, which not only leads to the increase of heat and the high temperature of the warehouse, but also the batch heat and cold exchange, which makes the tube groove of the refrigerator or cooler frosting, causing the temperature and temperature fluctuation of the goods, and damaging the storage quality of the goods. In order to reduce the cold consumption of the storehouse door, the following aspects should be taken into consideration:
1. Carry out targeted maintenance for the refrigerated door to ensure that the door can be opened and closed without any fault. Repair and maintain the characteristics of window sealing strip and heating wire, handle ice, frost and water all the time, maintain the air tightness test of the cold storage door, and avoid the vehicle hitting the warehouse door.
2. Try to avoid the times of opening and closing the door and the time of opening and closing the door, and ensure that the door is closed after entering and leaving.
3. Add cotton curtain or PVC soft curtain inside the door.
4. The air curtain is installed at the rear side of the chamber to ensure proper air velocity.
2、 Warehouse LED light control
The warehouse LED lights not only consume electricity, but also increase the heat of the storage space immediately. Therefore, the warehouse LED lights should be arranged in the front, middle and rear. The staff should avoid lighting frequency and time after entering the warehouse, and make sure to turn off the lights at will.
3、 Remove the dirt and frost on the heat exchange equipment on time to improve the heat transfer efficiency of the heat exchange equipment
4、 Reasonable selection and selection of grease
5、 Keep the refrigeration unit in its original condition
6、 Start the machine at night or at a lower temperature
7、 Reasonable collocation and comprehensive operation of storage types
8、 Ventilation application
9、 Maintenance of cold and damp proof course
10、 The harmony between refrigeration and industrial refrigeration is an important guarantee to reduce operating costs and improve economic benefits of enterprises
