Abstract
The utility model relates to a kind of engineering truck A/C, it comprises 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, in heat exchange chamber, be provided with H Exch, 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 utility model has is, in limited space, can realize refrigeration exchange, but also can save cost.
Description
Technical field
The utility model 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 utility model object 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 adopted in the utility model 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 utility model compared with prior art had is: the utility model is in the process using, first be first communicated with extraneous compressor and condenser, in the time of work, enter 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.
