Ruixue Refrigeration: Factors that determine the quality of cold storage installation
The factors affecting the quality of a cold storage are diverse. The following two factors have a great impact on the quality of the cold storage. When building a cold storage, as long as the direction is grasped, the quality of the entire cold storage installation can be guaranteed. The following Ruixue refrigeration for everyone to sort out the relevant content:
First of all, the cold storage installation of the cold storage refrigeration system is the core of the cold storage, and its choice is a vital part of the cold storage construction project. The refrigeration system is mainly composed of a compression system, a condensing system, an evaporation system and a regulating valve. In addition, there are accessories such as fans, pipes and meters. The entire refrigeration system is a sealed recirculation loop in which the refrigerant circulates, controlling the amount of supply and the number of passes into the evaporator as needed to achieve a suitable low temperature condition.
Under normal circumstances, the small cold storage is mainly based on fully enclosed compressors. Because the power consumption of the fully enclosed compressor is small, the price is relatively cheap; the medium-sized cold storage generally adopts a semi-closed compressor; the large-sized cold storage uses a semi-closed compressor. When selecting the cold storage evaporator, the high-temperature cold storage uses the cooling fan as the evaporator, which is characterized by rapid cooling, but it is easy to cause water loss in the cold collection; the medium and low temperature cold storage is mainly made of seamless steel pipe. It is characterized by a good thermostatic effect and can store cold in a timely manner. In the current cold storage installation industry, it is already a familiar experience of cold storage installation friends, but it is still worth paying attention to.
Secondly, the choice of insulation materials is also very important. The selection of cold storage insulation materials must be adapted to local conditions. It must have good thermal insulation properties and be economical and practical. Insulation materials are divided into several types. One can be sprayed with polyurethane foam, and the materials are directly sprayed into the existing built-in floor tiles or concrete warehouses. After shaping, they are both moisture-proof and heat-insulated. The heat insulating material plate has polyurethane, polyphenylene, and the like. Polyurethane does not absorb water and has good heat insulation, but it is costly in terms of the current cold storage installation market price; polyphenylene has strong water absorption and poor heat insulation, and currently has a low cost in the cold storage installation market.
The modern cold storage structure is developed in a positive assembly manner, and the warehouse body member including the moisture-proof layer and the heat-insulating layer is formed to achieve on-site assembly. The advantage is that the construction is convenient, fast, and movable, but the cost is relatively high. The other is processed into a fixed shape and specification of the floorboard, which has a fixed length, width and thickness. The floorboard of the corresponding specification can be selected according to the installation location of the cold storage warehouse. The high and medium temperature cold storage generally adopts a 10 cm thick basement board, and the low temperature cold storage And the frozen cold storage generally uses 12 cm or 15 cm thick floor blocks.
