The installation and system debugging strategy of cold storage refrigeration system

2. Assembly and installation of refrigeration unit 1. The semi-hermetic or hermetic compressor should be equipped with an oil separator, and an appropriate amount of oil should be added to the oil. When the evaporation temperature is lower than minus 15 degrees, a gas-liquid separator and an appropriate amount of refrigerating oil should be installed. 2. The base of the cold storage compressor should be equipped with a shock-absorbing rubber seat. 3. The installation of the unit should leave a maintenance space to facilitate the observation of the adjustment of the instrument and the valve 4. The high-pressure meter for cold storage installation should be installed at the three-way point of the liquid storage irrigation valve.

What kind of pre-cooling treatment should be done before the goods enter the cold storage?

The so-called pre-cooling mainly refers to a process in which various types of goods, such as food, can be stored in the cold storage from room temperature to 0°C, or close to the temperature of the storage cold storage. In this process, the rapid cooling process before cooling or rapid freezing is called pre-cooling.

Cold storage insulation materials and moisture-proof materials

Insulation materials for cold storage should meet the following conditions: 1. The thermal conductivity is small, so that a thinner thermal insulation layer can be used to obtain a better thermal insulation effect. 2. Low density and low price. 3. Good moisture resistance, frost resistance, firmness, high compressive strength, and durability to ensure long-term use. 4. Well thought out fire resistance, unnatural, and not supporting combustion, so as to improve the fireproof performance of the cold storage. 5. It does not produce any peculiar smell, does not absorb peculiar smell, and does not emit toxic substances, which is of great significance to food storage in cold storage. In addition, the cold storage insulation material should also have good corrosion resistance and not breed worms or other bacteria.

What is the reason for the power consumption of the cold storage? How to reduce electricity consumption in cold storage

1. First, let's take an example of food cold storage to analyze what factors will cause the increase in power consumption of cold storage: 1. Incorrect design of food cold storage-the design of the refrigerant connection pipe is too long, the cooling configuration of the unit does not meet the requirements, the thickness of the plate does not meet the standard, the low-temperature cold storage does not use aluminum row type, the external machine does not match the internal machine, and the cold storage adopts Conditions such as 220v electricity will increase power consumption. 2. Incorrect use of food cold storage-the goods are not pre-cooled before entering the storage with their own temperature, frequently entering and leaving the cold storage without opening the door without installing the air curtain, unreasonable stacking of incoming and outgoing goods, and irregular maintenance of the cold storage, etc. It will also lead to increased power consumption in cold storage.

Air-conditioned cold storage-no safety measures must be used with caution!

In recent years, cold storage safety accidents have occurred frequently, which has brought many hidden dangers to everyone's safety to a certain extent, and the safety of cold storage has been paid more and more attention. Air-conditioned storage is different from ordinary cold storage. The low-oxygen environment in the storage makes safety the top priority of the operation of the air-conditioned storage, and even has stricter safety requirements than some ordinary cold storage.

Management and Application of Cold Storage Automation

Functions after equipment transformation: (1) The upper computer management and control of the entire cold storage system. On the upper computer, the temperature of each cooling room of the cold storage, the operating status of the compressor, and the working status of each point of the equipment are displayed on the upper computer in real time, such as equipment start and stop, operation, failure, and valve control. Status, set temperature value and actual control value of each cold room, etc., record the temperature of each cold room with a curve, and the operating load current of the compressor. Real-time monitoring and alarming of parameters such as temperature and pressure, display of parameters such as return valve pressure and operation of operating equipment. It has the process temperature for storing different storages in different refrigeration rooms, and sets the process parameter database such as storage temperature and refrigeration capacity (return air pressure) for users to call.

ODS refrigerant replacement technology has a long way to go

In order to protect the ozone layer and slow down global warming, the replacement and conversion of ODS refrigerants has become a major environmental protection issue faced by the global refrigeration and air-conditioning industry. Through the joint efforts of all sectors of society, since July 1, 2007, my country has completely stopped the production and consumption of HCFCs. According to the resolution of the Conference of the Parties to the Montreal Protocol held in Montreal, Canada in September this year, for developing countries including China, the production and consumption of HCFCs will be frozen at the average levels of 2009 and 2010 in 2013. To complete the complete phase-out in 2030,
