摘要:
The air conditioner capacitor is arranged at the front side of the oil cooler or the radiator against the flow of the cooling air, thereby carrying out maintenance of the oil cooler and/or the radiator at the rear side without removing the air conditioner capacitor arranged at the front side, thus improving maintenance. The turbocharger cooler 11 is structured to change the postures so as to swing up and down between the cooling posture in which the turbocharger cooler 11 is arranged in parallel with the radiator 8 and an open posture in which the turbocharger cooler 11 is arranged such that the front side of the radiator 8 is exposed. The air conditioner capacitor 10 and the oil cooler 9 are also structured to change the postures so as to swing horizontally between the cooling posture in which the air conditioner capacitor 10 and the oil cooler 9 are arranged in parallel with the radiator 8 and an open posture in which the air conditioner capacitor 10 and the oil cooler 9 are arranged such that the front side of the radiator 8 is exposed.
摘要:
The invention provides an air-conditioning apparatus that maximizes the space in an operator's cab and provides a comfortable working environment for the operator of a construction machine. The body unit of the air-conditioning apparatus is disposed under the floor surface of the cab, cold air and hot air ducts are connected to the body unit, and routed under the floor of the cab to be passed through the floor surface and taken out into the inside of the cab using cold air and hot air outlets disposed at both left and right sides at the front part of the cab. Also, by providing two evaporators, air of different temperatures can be blown through the left and right outlets.
