Abstract
The invention relates to an air conditioner for an engineering vehicle. The air conditioner comprises a shell, wherein the shell consists of a lower shell and an upper shell matched with the lower shell, a fan bin and a heat exchanging cavity are arranged in the lower shell, a lower outlet is formed in the bottom of the lower shell, a fan is arranged in the fan bin, and a heat exchanger is arranged in the heat exchanging cavity. The air conditioner is characterized by further comprising an evaporator core and an expansion valve, wherein a refrigerating exchanging cavity is arranged between the fan bin and the heat exchanging cavity, the evaporator core (concurrent flow) is arranged in the refrigerating exchanging cavity, the expansion valve communicated with the evaporator core is arranged on one side of the evaporator core, and lateral air outlets communicated with the shell are symmetrically arranged on two side faces of the shell. The air conditioner has the advantages that the refrigeration exchanging can be realized in a limited space, and the cost can be further lowered.
Description
Technical field
The present invention relates to automotive field, particularly a kind of engineering truck A/C.
Background technology
In the engine nacelle of current existing large engineering vehicle, A/C is installed, and existing A/C use process in only to give off warm braw, people is in the process of work like this, can not feel well, make to heat and freeze existence simultaneously and cannot realize in limited space, if increase a cooling air unit in engine nacelle, just engine nacelle need to be expanded, thereby increase cost.And existing heater air output in the process using is smaller.
Summary of the invention
For above-mentioned shortcoming, the object of the invention is to provide a kind of can realize the engineering truck A/C that heats and freeze exchange in limited space simultaneously.
For achieving the above object, the technical solution used in the present invention is: a kind of engineering truck A/C, comprise shell, shell forms by lower house with the matching used upper shell of lower house, in described lower house, be provided with blower fan storehouse, heat exchange chamber and be arranged on the lower outlet of lower house bottom, described blower fan is provided with blower fan in storehouse, is provided with H Exch in heat exchange chamber, it is characterized in that it also comprises evaporator core and expansion valve; Between described blower fan storehouse and heat exchange chamber, be provided with refrigeration inverting chamber, in refrigeration inverting chamber, be provided with evaporator core (parallel flow), one side of evaporator core is provided with the expansion valve being communicated with evaporator core, and the two sides of described shell are arranged with the side air-out mouth being communicated with shell.
The advantage that the present invention compared with prior art had is: the present invention, in the process using, is first first communicated with extraneous compressor and condenser, in the time of work, enters condenser from compressor high temperature, high-pressure refrigerant out by high pressure hose.Because the outer temperature of car is lower than the refrigerant temperature that enters condenser, by means of the effect of condenser fan, the amount of heat of the refrigerant in condenser is taken away by car outer air, thereby high temperature, high pressure gas are condensed into the liquid of high temperature, high pressure.This high temperature, when highly pressurised liquid flows through expansion valve assembly, due to throttling action, volume becomes suddenly greatly and step-down, become low temperature, the spray (liquid) of low pressure enters evaporator, under level pressure, vaporize, due to refrigerant pipe in vaporize time temperature lower than the car outside evaporator tube in circulated air, therefore heat in its energy automatic absorption pipe outer air, thereby the air themperature of the evaporator that makes to flow through reduces, produce the effect of refrigeration cool-down, the refrigerant of having vaporized is by compressor suction compression, become high temperature, the gas of high pressure, be sent to condenser by high pressure hose again, so just complete the thermodynamic cycle of a refrigeration system.In limited space, just can realize refrigeration exchange like this, can save like this cost, and on shell, be provided with both sides air outlet, can increase like this air quantity of air-out, thereby make the better effects if of refrigeration.
