Cooling and heating type variable frequency air conditioner of pure electric bus

Abstract

The invention provides a cooling and heating type variable frequency air conditioner of a pure electric bus. The cooling and heating type variable frequency air conditioner of the pure electric bus comprises a first partition plate and a second partition plate which are arranged on the lower side and the upper side of a condenser, the condenser is obliquely arranged with the front end higher than the rear end, the bottom of the first partition plate is abut against a bottom shell while the top thereof is abut against the condenser, the bottom of the second partition plate is abut against the condenser while the top thereof is abut against a top cover, the condenser is separated into a front section, a middle section and a rear section by the first partition plate and the second partition plate, and a condenser fan is arranged behind the second partition plate. During running of the bus, cool air enters via air vents, detours three times under the action of the partition plates, flows through the condenser and then is drawn out from the condenser fan, and then heat of the condenser fan can be brought away fully. Compared with the prior art, air flowing amount for unit area of the condenser is increased by three times, and cooling effect of the condenser fan is greatly strengthened under the condition of same air drawing amount.

Description

technical field [0001] The invention relates to a passenger car air conditioner, in particular to a pure electric passenger car cooling and heating type frequency conversion air conditioner. Background technique [0002] The passenger car air conditioning system is a device that realizes cooling, heating, ventilation and air purification of the air in the passenger car. It can provide a comfortable riding environment for the passengers, reduce the driver's fatigue intensity and improve driving safety. The air conditioning unit has become one of the symbols to measure whether the car is fully functional. With the development of my country's urban public transport and tourism, a large number of air-conditioned buses are on the market, and there is an increasing demand for passenger car air-conditioning maintenance personnel. Compared with cars, passenger car air conditioners are a system of their own. The passenger car air conditioning system is composed of refrigeration...
