Computer room air conditioning refrigerant leakage

it is well known that large equipment power density of high calorific value, so the volume data exchange, such as computer room still needs through constant refrigeration air-conditioning compressor to meet the needs of communications equipment to the environment temperature, the refrigerant through the pump running, the ethylene glycol solution as the carrier of cold agent for indoor and outdoor heat exchanger, prevent air conditioning compressor work, because the computer room precision air conditioning evaporator left and right sides of the joint is more, the likely funnelled more also, precision air conditioning refrigerant leakage is often the case, the main reason is that air conditioner factory employees poor welding technology, in the absence of the burn (red copper pipe Did not reach a temperature of 600 ℃ ~ 700 ℃) , just put the electrode in joint, copper tube and solder was not able to fuse together, causing joint holder welding, MaZha, leakage is not smooth, look at this several air conditioning refrigerant leakage point below how to patching.

room for the newly installed the air conditioner, close the end of the valve, outdoor atmosphere to eliminate indoor machine, indoor machine evaporator leakage ring accidentally use ears to hear, visible leaking air conditioner, evaporator solder joints is put into a neglected, invented the evaporator leakage, the best welding, it lest the evaporator heat plastic shell deformation, helpless to the user account, assembly method is:

1, get funnelled, ready to sign.

2, if otherwise refrigerant refrigeration system, must first put the refrigerant charge exists in outdoor.

3, with two 8 or 10 inches spanner remove indoor machine join lock mother, remove indoor machine electrical box on the right.

4, unload evaporator back line, plywood, you positioning screw down the indoor evaporator.

is a modern air conditioner capacitor widely used in start capacitor suppliers industry. It also enhances the quality start capacitor suppliers value of the products.

Hangzhou E cool refrigeration Co.,Ltd will be familiar with the transformation from a generalist into a manufacturer, and will have the big-picture perspective necessary to stay focused on long-term goals.

Hangzhou E cool refrigeration Co.,Ltd will give you a suitable price for purchasing refrigerant gas.

Undoubtedly, air conditioner capacitor are made with advanced equipment.
