Title: Air conditioner for vehicle
Inventor: KURODA YASUTAKA
IPC: F25B9/00
Filed: 2001-10-29
Abstract: PROBLEM TO BE SOLVED: To suppress an increase of manufacturing cost of a heat exchanger such as an indoor heat exchanger while suppressing degradation of an air- conditioning feeling. SOLUTION: When a hot water temperature Tw is less than a predetermined temperature Two, a heat pump device 10 is operated with a maximum heating capacity within a limit of a withstand pressure of the indoor heat exchanger 15. When the hot water temperature Tw is more than the predetermined temperature Two, a heating capacity of the heat pump device 10 is decreased in response to an increase of the hot water temperature Tw. Thereby, high pressure coolant does not continuously flow in the indoor heat exchanger 15 over a long period of time, thus a necessary and sufficient withstand pressure capacity can be obtained without setting a proof pressure of the indoor heat exchanger 15 at an excessively high pressure.  Furthermore, because heating quantity to air by the indoor heat exchanger 15 and heating quantity to the air by a heater core 21 are controlled based on the predetermined temperature Two, a blowout air temperature can be set at an approximately target blowing temperature without depending on the pressure of the high pressure coolant and fluctuation of the hot water temperature Tw.
