PURPOSE:To make even the temperature partially distributed in a cabin by providing two systems consisting of a right side and a left side refrigerating cycle so as to control the temperature in the right and left sides of the cabin independently in a package type air conditioner for buses and the like. CONSTITUTION:This air conditioner is provided with two refrigerating cycles 100 and 200 for the right and left side use of a cabin. Each of refrigerating cycles 100 and 200 includes each of compressors 11 and 12 driven by an engine, each of condensors 21 and 22, each of pressure reducers 31 and 32, and each of evaporators 41 and 42, and each of them is connected with pipes to form each of closed cycles. And they are all contained is a cooler case 7 which is installed on the roof of a vehicle, as an integral unit. And two cooling ducts which extend back and forth, are provided on both sides of the vehicle, and cool air from each of the evaporators 41 and 42 is inducted into each of the ducts through a right and a left cool air outlet 741 and 742. And the coolant flow in each of refrigerating cycles 100 and 200 is automatically controlled based on the output from temperature detecting means arranged on the right and left sides of the cabin. |
