Air conditioner of double-decker bus

Abstract

The invention relates to an air conditioner of a double-decker bus, which comprises a rack, a compressor, a condenser, a condensing fan, a liquid storage device, a dryer, a sight glass, an expansion valve, an evaporator, an evaporating fan, a cooper pipeline and the like, wherein the whole rack is a layered framework structure, and the upper layer is the evaporator part which is provided with theevaporator, the evaporating fan and the corresponding structure; the lower layer is the condenser part which is provided with the condenser, the condensing fan, the liquid storage device, a condensedwater heat recovery device, the dryer, the sight glass, the expansion valve and the corresponding structure; and the large-displacement compressor is adopted and connected with the condenser and the evaporator through a connecting pipe for carrying out refrigeration cycles. The air conditioner of the double-decker bus has the positive effects that the air conditioner has the simplified overall framework type structure, thereby having strong applicability; and the air conditioner can meet the needs on refrigerating capacity of different bus types by adjusting the heat exchange areas of the condenser and the evaporator, and reasonably utilize condensed water for carrying out heat recovery, thereby leading the cooling effect to be better, further improving the refrigerating capacity and the refrigeration coefficient, leading the mounting and the maintenance to be convenient, having low cost, replacing imported products and having great application prospects.

Description

【Technical field】 [0001] The invention relates to the technical field of auto parts, in particular to the manufacturing technology of an automobile air conditioner, in particular to an air conditioner for a double-decker bus or a large passenger car. 【Background technique】 [0002] The double-decker buses mentioned here mainly include 11-12-meter double-decker buses, 13.7-meter one-and-a-half-story tourist buses and 12-meter one-and-a-half-story tourist buses. [0003] At present, the air conditioners of double-decker buses in my country are mainly imported from Japan. The domestic products are not yet perfect, and most of them are sheet metal assembled structures. Generally speaking, the cooling capacity of existing double-decker bus air conditioners is relatively low, the evaporative air volume is relatively small, and the front and rear air supply is uneven. Vehicle cooling load under current driving conditions. In addition, the sheet metal assembly structure is adopted...

AI Technical Summary

Problems solved by technology

Generally speaking, the cooling capacity of existing double-decker bus air conditioners is relatively low, the evaporative air volume is relatively small, and the front and rear air supply is uneven. Vehicle cooling load under current driving conditions

In addition, the sheet metal assembled structure is used, which makes assembly and maintenance poor

Japan's Denso integral imported air conditioner is expensive, and it uses three small-displacement compressors, with low cooling capacity (COP), complex system structure, high failure rate, and difficult maintenance
