The way to save the cost of cold storage installation is to reduce meaningless expenditure and interference.
1. Reasonable selection of the cooling range of the cold storage not only determines the use range of the cold room but also has a great impact on the installation cost. The lower the design temperature of cold storage installation is, the higher the requirement of refrigeration equipment is, and the higher the cost of cold storage installation is. Reasonable selection of the cooling range of cold storage is very helpful to control the installation cost of cold storage and reduce investment waste. For example, the temperature of fruit preservation is generally no less than 0 ℃, only a few varieties are required to reach - 1 ℃, and the suitable preservation temperature of many tropical fruits is 5 ℃ or even above 10 ℃. All fruit preservation refrigerators are generally designed with the lowest temperature of 0 ℃, if there is no problem, 5 ℃ can also be used as the design temperature.
2. The relationship between the number of condensing unit for cold room and the cost is very flexible. We can achieve the same refrigeration effect by configuring different types and numbers of units. In small and medium-sized cold storage, the cost of a single unit is generally lower than that of multi-unit, but when the refrigeration capacity of cold storage reaches a certain degree, the demand for equipment is higher, and the price of a single unit will be higher than that of multi-unit. Therefore, when choosing the cold storage plan, we should not only consider the idea that parallel units are more stable, more energy-saving or more convenient, but also consider the comprehensive installation cost and operation cost.
3. If the height of storehouse is designed properly, if the height of storehouse is higher than 5m, to ensure that the structure of storehouse top is not damaged, materials such as hanging parts shall be used to reinforce the storehouse top for cold storage installation, which will increase the installation cost and labor cost, and may also generate some use costs of machinery (such as crane).
4. The effective use of natural resources water-cooled units does not have high requirements for cooling water. Clean, no impurity and corrosive water can be used. If the cold storage installation site is close to the natural water source or located in the place where the water supply system already exists, such as the ship, factory, etc., the water-cooled unit can be selected to directly use the existing water supply system. The price of the water-cooled unit is lower than that of the air-cooled unit. If the water pump, water pipe, and other equipment are not required, the installation cost of the cold storage can be reduced. This method can reduce the cost of cold storage and improve the refrigeration efficiency of the cold storage.
