Because the utility model discloses vehicle defrosting wind channel has adopted porous medium layer, consequently conveniently sets up according to the structure of vehicle, consequently is fit for setting up in the instrument desk of vehicle, in the door or near other glass that need the defrosting.
The utility model also provides a vehicle air conditioner defrost system, include:
an air conditioning system; and
above-mentioned the utility model discloses vehicle defrosting wind channel.
The air duct inlet of the vehicle defrosting air duct is connected with an air outlet of the air conditioning system.
For a detailed description of the vehicle defrosting duct, reference may be made to the foregoing embodiments, and for the sake of brevity, detailed description is omitted here.
The heated air of the air conditioning system is supplied to an air duct inlet of the defrosting air duct, and is uniformly blown to the inner side of the glass through the defrosting air duct to defrost.
The air conditioning system can comprise 5 basic components of a refrigerating system, a heating system, a ventilation system, a control system and an air purification system.
(1) A refrigeration system:
the refrigerating system cools the air in the passenger room or the fresh air entering the passenger room from the outside, and achieves the purpose of reducing the temperature in the passenger room. The evaporator, which is a heat sink, has a temperature lower than the dew point temperature of the air, and thus the refrigeration system also has the function of dehumidifying and purifying the air.
(2) A warm air system:
in a vehicle warm air system, a coolant of an engine is generally introduced into a cabin heater, and heated air is blown into a cabin by a blower to raise the temperature of the air in the cabin. Meanwhile, the front windshield glass can be defrosted and demisted.
(3) A ventilation system:
ventilation is generally classified into natural ventilation and forced ventilation. The natural ventilation is realized by arranging an air inlet and an air outlet at proper places according to different wind pressures generated outside a vehicle when the vehicle runs; forced ventilation is a method of forcibly introducing outside air into a passenger compartment using a blower, which is often operated together with natural ventilation when a vehicle is running. The ventilation system is provided with an air treatment chamber, an air supply duct, a damper, and the like.
(4) An air purification system:
the air purification system generally comprises an air filter, an air outlet and the like, and is used for filtering air introduced into the passenger compartment, continuously discharging dirty air in the passenger compartment and keeping the air in the passenger compartment clean.
(5) The control system comprises:
the control system mainly comprises an electric element, a vacuum pipeline and an operating mechanism. The air conditioner is mainly used for controlling the temperature and the pressure of a refrigerating and heating system and controlling the temperature, the air quantity and the flow direction of air in a passenger room, and perfecting various functions of the air conditioner system. On large and medium-sized passenger cars, the systems are usually independently installed and used independently. If 2 or 3 independent forced ventilation fans are installed on the roof of the vehicle for ventilation in the passenger compartment, an independent fuel combustion type heater is used for heating the passenger compartment in winter, and an independent refrigerating system driven by a special auxiliary engine (air-conditioning engine) is used for providing cold air for the passenger compartment in summer.
The air conditioning system may be a non-independent air conditioning system or an independent air conditioning system.
The power for driving the compressor of the non-independent air conditioning system comes from the main engine, namely the power required by the air conditioner and the power for driving the vehicle come from one engine. Most cars, small and medium size passenger cars and trucks can adopt non-independent air conditioning systems.
The independent air conditioning system adopts a special engine to drive the refrigeration compressor, namely, a main engine drives a vehicle to move forward, and the special engine drives the compressor. The large bus and the luxury large and medium buses can adopt independent air conditioning systems.
The non-independent air conditioning system affects the dynamic performance of the vehicle, but is more economical in equipment cost and operation cost compared with the independent air conditioning system.
Optionally, in an embodiment of the present invention, the air duct inlet of the vehicle defrosting air duct is connected to an air outlet of a warm air system of the air conditioning system. When defrosting is needed, hot air in the warm air system is blown to the inner side of the glass through the defrosting air duct to defrost.
Therefore, the utility model discloses vehicle air conditioner defrost system except can adjusting temperature, humidity, the air velocity in the car, and outside the air-purifying, can also detach fog, frost, ice etc. on the windscreen, consequently can provide an environment suitable to the human body to can give a clear field of vision of driver, ensure driving safety.
