Precautions for installation and use of compressor-type car refrigerator

Precautions for installation and use of compressor-type car refrigerator A car refrigerator is a refrigerator that can be carried on a car. Car refrigerator is a new generation of cold storage appliances popular in the international market. Compressor car refrigerators are similar to household refrigerators. They are all cooled by compressor power. The refrigeration is fast and powerful. The refrigeration can reach -18 ℃. It can make ice and keep fresh. The volume can be large or small. The mainstream direction of the development of car refrigerators. Compressor-mounted refrigerators can be used in cars or can be used for home use through power converters, which is an extension and supplement of home refrigerators. The characteristic is portable and mobile, and it is also a car product suitable for self-driving. Its principle is to obtain liquid refrigerant through mechanical compression (compressor), convection heat exchange (condenser), and throttling and depressurization (capillary). The liquid refrigerant evaporates into a gaseous state (evaporator) in the refrigerator box, through phase change Take away the heat in the box, so as to achieve the cooling effect; finally, the gaseous refrigerant returns to the compressor; repeat the above process, the refrigeration system continuously moves the heat in the box to the outside of the box with the energy source, so as to achieve the cooling effect. Installation and use method of compressor-type car refrigerator: ① How to install and use in the car a. When used in the car, the box needs to be fixed in a suitable position in the car, and maintain good ventilation. b. Put the "AC, DC" switch in the DC block; select the "cold/hot" switch block, the corresponding indicator light is on, and the machine starts to work. c. Insert one end of the DC power cord into the DC jack on the refrigerator and the other end into the 12V cigarette lighter socket in the car. The current should be greater than 5A. d. Put the "Refrigeration, Heating" switch in the open gear, or put the "AC, DC" switch in the open gear, the machine will stop working. e. During heating, when the temperature in the box rises to 70℃±5℃, the power will be automatically cut off, and when the temperature is lower than 60℃±5℃, the power will automatically turn on to continue heating. ②How to install and use at home a. Plug one end of the AC power cord into the AC jack on the refrigerator and the other end into the 220V AC power socket. b. Set the "AC, DC" switch to AC gear; select the "cold/hot" switch gear, the corresponding indicator lights, and the machine starts to work. c. Put the cooling and heating selector switch in the close block, or put the AC and DC switch in the close block, the machine can stop working. d. During heating, when the temperature in the box rises to 70℃±5℃, the power will be automatically cut off. When the temperature is lower than 60℃±5℃, the power will automatically turn on to continue heating. Pay attention to the following matters when installing and using the car refrigerator 1. When the car refrigerator is used in a car, it can only use 12V DC 2. The vents and heat dissipation holes should be kept clear. 3. In the heating working state, the box is suitable for storing heated food, but not suitable for storing frozen food. 4. When switching from the heating function, the power should be turned off and restarted after 5 minutes.
