Abstract
The utility model provides a non joint sealed bus air conditioner which comprises a compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator and an air blower. The compressor, the condenser, the liquid storage dryer, the expansion valve and the evaporator are connected to form a sealed system through pipelines. The pipelines are integrated and connection of each part is in a welded mode. No leakage is achieved through the integral pipelines and welding among the pipelines and the parts. No matter in what condition, a bus travels on a bumpy road, or condensing evaporating liquid is small in interfacial tension, leakage can not happen, the safety of traveling of the bus is guaranteed, and the maintenance cycle of the bus is shortened.
Description
Technical field
The utility model relates to a kind of coach air conditioner, especially a kind of non junction Sealed Passenger Car air-conditioning.
Background technology
Hvac system be realize to air in a car compartment freeze, the device of heating, ventilation and air cleaning.It can reduce driver's fatigue strength for rider person provides comfortable by bus environment, improves traffic safety.Aircondition has become weighs whether one of complete sign of automobile function.Along with the development of China's city bus and tourist industry, air-conditioned passenger train goes on the market in a large number, and the coach air conditioner maintenance personal has been had increasing demand.Relative car, coach air conditioner has an individual system of one's own.Hvac system is by refrigeration system, heating system, ventilation and air cleaning unit and composition of the control system.The coach air conditioner refrigeration system is comprised of compressor, condenser, drier receiver, expansion valve, evaporimeter and air blast etc.The condensation of condenser refers to refrigerant loses heat in its pipeline from the gaseous state liquid state of congealing into.The cooling water tank of its principle and engine close (difference only is that the water of water tank is liquid always), so it often is installed in headstock, with water tank, the common breezy cool breeze of enjoying from the place ahead.Condenser is where to cool off oneself where to go in a word, so that its heat radiation condensation.Evaporimeter is just in time opposite with condenser, and it is cold-producing medium is become gaseous state (i.e. evaporation) absorbing heat by liquid state place.Adopt copper pipe (or aluminum pipe) and high-pressure rubber hose to connect into a closed system between each parts.During refrigeration system work, cold-producing medium circulates in this closed system with different states, each circulation is four basic processes again: 1, compression process: compressor sucks the refrigerant gas of the low-temp low-pressure at evaporator outlet place, and the gas that it is compressed into HTHP is discharged compressor.2, heat radiation process: the superheated refrigerant gas of HTHP enters condenser, because the reduction of pressure and temperature, refrigerant gas is condensed into liquid, and discharges a large amount of heats.3, throttling process: the refrigerant liquid that temperature and pressure is higher becomes large by volume behind the expansion gear, and pressure and temperature sharply descends, and discharges expansion gear with vaporific (fine drop).4, endothermic process: atomized refrigerant liquid enters evaporimeter, thus the time cold-producing medium boiling point far below temperature in the evaporimeter, so refrigerant liquid flashes to gas.Heat in evaporation process around a large amount of the absorption, then the refrigerant vapour of low-temp low-pressure enters again compressor.The carrying out that said process goes round and begins again reaches the purpose that reduces the evaporimeter ambient air temperature.
Existing coach air conditioner adopts copper pipe (or aluminum pipe) to connect into a closed system between each parts, because pipeline often needs bending, be threaded in its bending place employing, sealing, also is to adopt to be threaded in addition between pipeline and each parts, seals.The shortcoming that this design exists is, exists easily poorly sealedly, leaks, and especially passenger vehicle is under the long-distance state that jolts, and leak case takes place frequently especially.In addition since in the recent period the condensation evaporation liquid in the pipeline for environmental protection, employing be the less condensation evaporation liquid of interfacial tension, exosmose so it is more prone to reveal.
The utility model content
Problem to be solved in the utility model is to improve the problem that the condensation evaporation liquid of background technology microbus air-conditioning leaks easily.
In order to overcome the above problems, the utility model provides a kind of non junction Sealed Passenger Car air-conditioning, comprise compressor, condenser, drier receiver, expansion valve, evaporimeter and air blast, adopt pipeline to connect into a closed system between described compressor, condenser, drier receiver, expansion valve, the evaporimeter, that described pipeline is integrated and and each parts between be connected to welding.
Described device for cleaning pipeline is crossed welding and the shape all-in-one-piece.
Described pipeline is copper or aluminium material.
Non junction Sealed Passenger Car air-conditioning described in the utility model, comprise compressor, condenser, drier receiver, expansion valve, evaporimeter and air blast, described compressor, condenser, drier receiver, expansion valve, adopt pipeline to connect into a closed system between the evaporimeter, that described pipeline is integrated and and each parts between be connected to welding, by the pipeline of one and the welding between pipeline and each parts, realize without leaking, no matter be that bus driving is on the road of jolting, or the less condensation evaporation liquid of interfacial tension, can not leak, guarantee the passenger vehicle Operation safety, reduced the cycle of passenger vehicle maintenance.
Description of drawings
Accompanying drawing 1 is the pipeline schematic diagram of non junction Sealed Passenger Car air-conditioning part described in the utility model
1, pipeline.
The specific embodiment
Below in conjunction with accompanying drawing a kind of non junction Sealed Passenger Car of the utility model air-conditioning is described further.
As shown in fig. 1, the non junction Sealed Passenger Car air-conditioning of present embodiment, comprise compressor, condenser, drier receiver, expansion valve, evaporimeter and air blast, adopt pipeline 1 to connect into a closed system between compressor, condenser, drier receiver, expansion valve, the evaporimeter, pipeline 1 that be integrated and and each parts between be connected to welding.By the pipeline of one and the welding between pipeline and each parts, realize no matter being that bus driving is on the road of jolting without leaking, or the less condensation evaporation liquid of interfacial tension, can not leak, guarantee the passenger vehicle Operation safety, reduce the cycle of passenger vehicle maintenance.
The non junction Sealed Passenger Car air-conditioning of present embodiment, pipeline 1 is the shape all-in-one-piece by welding.Certainly, also can be transformed to direct bending all-in-one-piece, although the technique more complicated, its performance can be guaranteed.In the present embodiment, described non junction Sealed Passenger Car air-conditioning, pipeline 1 is copper or aluminium material.This material is that heat conduction is fast, guarantees that the operating heat radiation system of air-conditioning is good.
The utility model is not limited to above embodiment and conversion.
