Description

Technical Field

[0001] The utility model relates to the technical field of chillers, in particular to a chiller for a variable-frequency energy-saving air conditioner. Background Art

[0002] A variable-frequency energy-saving air conditioner is an air-conditioning system using variable-frequency technology, which can automatically adjust the cooling or heating power and operating frequency to adapt to the change of indoor temperature. Compared with the traditional fixed-frequency air conditioner, the variable-frequency energy-saving air conditioner has the advantages of energy saving and high efficiency, stable temperature, noise reduction and quietness, so it is widely used.

[0003] During the operation of the existing chiller for an air conditioner, a exhaust fan is needed to improve the heat dissipation efficiency of the condenser. However, after the equipment is used for a long time, a large amount of dust is easily attached to the surface of the exhaust fan, and the dust will greatly reduce the heat dissipation efficiency of the exhaust fan, thereby reducing the working efficiency of the chiller, increasing the energy consumption of the chiller. Moreover, since the chiller is located inside the air conditioner, it is not very convenient for the staff to perform maintenance, wasting a lot of time costs. Summary of the Utility Model

Thus, the cold water machine case 201 is driven to move through the second swing rod 205d, so that its front end extends out of the protection box 101, which is more convenient for maintenance personnel to maintain and repair the cold water machine case 201.

[0033] During use, when maintenance or repair of the cold water machine case 201 is required, pull the handle 106 to both sides. Drive the door 104 to open to both sides through the slider 105. The door 104 drives the first connecting rod 205b to rotate. The first connecting rod 205b drives the sector gear 205a to rotate. The rotation of the sector gear 205a drives the first swing rod 205c to move accordingly. Furthermore, the second swing rod 205d drives the cold water machine case 201 to move outside the protection box 101, thus facilitating the maintenance by the staff. After the equipment has been working for a period of time, a large amount of dust adheres to the exhaust fan 206d, affecting the heat dissipation effect of the cold water unit. At this time, turn on the motor 210. The output end of the motor 210 drives the rotating shaft 206a to rotate. The rotating shaft 206a drives the dust cleaning brush 206c to clean the exhaust fan 206d, causing the dust to fall off into the collection box 207. Subsequently, rotate the threaded rod 209d so that the front end of the rectangular block 209c disengages from the card slot opened at the end of the connecting plate 208. Then, the connecting plate 208 can be pulled to drive the collection box 207 out of the interior of the protection box 101, and the dust in the collection box 207 can be cleaned up.
