Abstract

The utility model relates to an air conditioner for a passenger vehicle, in particular to a novel air-conditioning and refrigerating device for the passenger vehicle. The adopted technical scheme is as follows: the novel air-conditioning and refrigerating device for the passenger vehicle comprises an air outlet in the vicinity of a luggage rack and a dashboard air outlet, and is characterized in that the air-conditioning and refrigerating device further comprises the air outlet behind an engine. The novel air-conditioning and refrigerating device has the benefits that, as the air outlet of the refrigerating device is mounted at the tail part of the vehicle, cold air blown out thorough the air outlet and heat generated by the engine and other devices can offset mutually, thereby reducing the impacts of the heat produced by the engine and other devices on temperature in a compartment. The cold air which is blown out through the air outlets of the refrigerating device is blown onto a floor in the compartment, thereby reducing the temperature of the floor and the temperature above the floor, leading the temperature in the compartment to be more appropriate, simultaneously reducing the temperature around the engine, bringing more appropriate sitting environment to passengers at the back part, and simultaneously bringing good working environment to the engine.

Description

The new type passenger car air-conditioning refrigeration plant

Technical field

The utility model relates to a kind of coach air conditioner, especially relates to a kind of new type passenger car air-conditioning refrigeration plant.

Background technology

Rear-mounted engine is the most popular engine position mode of present motor omnibus and part medium bus, such arrangement has well solved the shortcoming that F/F showed: the floor level that has reduced the compartment, especially for bus, can accomplish that one-level marks time, it is very convenient to get on or off the bus; The noise of driving engine has also obtained actv. control, and the front portion of vehicle is very quiet, and the sealing in compartment also improves certainly greatly.But after having adopted rear-mounted engine, driving engine, change-speed box, these bigger devices of retarder are all at the rear portion of vehicle, can produce a large amount of heats in the process of these device busies, particularly the heat that produces after the engine long time service has no idea to distribute at short notice, the temperature of the temperature that will make lower rear in the compartment other parts in the compartment.And the air outlet of the Refrigerating for passenger train device that adopts now generally be placed in car body top two ends (generally shelf near), and the afterbody of automobile does not generally all have the air outlet of refrigeration system, this is with regard to the fridge equipment that makes automobile have no idea well the to regulate temperature of automobile tail, the temperature drift of automobile rear when thereby the temperature that causes automotive front is relatively more suitable, the passenger who particularly is sitting in driving engine top can feel that the relatively more nice and cool and below of wind that the air outlet of top blows out is because the influence of device liberated heats such as driving engine can be felt comparative heat, the environment of adding automobile tail itself just is not so good as the good of front portion, thereby can make the passenger who is sitting in the compartment afterbody for a long time feel very uncomfortable.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, can solve the too high new type passenger car fridge equipment of compartment afterbody temperature by actv. and provide a kind of, by the refrigeration of the vent window of fridge equipment with the enhancing automobile tail is installed at the afterbody in compartment, thereby slacken heat that device such as driving engine produces to Temperature Influence in the compartment, reduce front and back, temperature contrast up and down in the compartment, and then reach desirable refrigeration.The technical scheme that adopts is: a kind of new type passenger car air-conditioning refrigeration plant, comprise near air outlet of baggage rack and gauge panel air outlet, and it is characterized in that: described air-conditioning refrigeration plant also comprises driving engine rear air outlet.

Described fridge equipment also comprises back seat below air outlet.

The beneficial effects of the utility model are: the utility model has been installed the air outlet of fridge equipment at the afterbody of automobile, the heat that devices such as cold wind that blows out by air outlet and driving engine produce is cancelled out each other, thereby reduces heat that device such as driving engine produces to Temperature Influence in the compartment.The cold wind that air outlet by fridge equipment blows out blows on the floor in the compartment, thereby reduced the temperature of floor and floor top, make the temperature in the compartment more suitable, also reduced simultaneously driving engine temperature on every side, brought the suitable more environment of taking to back occupant, also brought good working environment simultaneously to driving engine.

Description of drawings

Fig. 1 is the utility model structural representation;

Wherein, 1. driving engine top air outlet; 2. back seat below air outlet; 3. near the air outlet baggage rack; 4. instrument desk air outlet.

The specific embodiment

In conjunction with the accompanying drawings, the utility model is elaborated.The air-conditioner air outlet of this air-conditioning fridge equipment comprises driving engine top air outlet 1, back seat below air outlet 2, near the air outlet 3 of baggage rack and instrument desk air outlet 4, wherein, back seat below air outlet 2 should be noted allowing wind direction avoid the passenger when arranging the air port, can select straight below or floor to seat, wind speed should be slightly less than near the wind speed of the air outlet 3 of baggage rack.Driving engine top air outlet 1 has reduced the heat of other equipment in running conditions generations such as driving engine to Temperature Influence in the compartment, like this, the air outlet that afterbody in the compartment increases can effectively reduce the temperature of compartment afterbody, makes the temperature basically identical of front and back, compartment, has increased the traveling comfort of taking.

Claims

1. A kind of new type passenger car air-conditioning refrigeration plant comprises the air outlet and the gauge panel air outlet that are arranged on the baggage rack place, and it is characterized in that: described air-conditioning refrigeration plant also comprises the air outlet that is arranged on the driving engine rear.

2. according to the described new type passenger car air-conditioning refrigeration plant of claim 1, it is characterized in that: described fridge equipment also comprises the air outlet that is arranged on the back seat below.
