Abstract: An integrated cooling, heating, and dehumidizing air-conditioning system for an electric vehicle includes an inverter compressor, a four-way valve connected to the inverter compressor, first, second, and third heat exchangers connected to the four-way valve, a three-way valve connected to the heat exchanger, a ring-shaped thermoelectric heater connected to the inverter compressor and the second heat exchanger, an expansion valve connected to the second and third heat exchangers, and a check value connected to the first, second, and third heat exchangers, so that the air-conditioning system provides different refrigeration and heating methods operated according to the requirements of a driver and passengers and switched according to different climates.

Abstract: This invention relates to an internal jet impingement type shell and tube heat exchanger in which the jet cooling tubes and the heating tubes in shell and tube heat exchanger are formed either as a staggered tube bundle or as a square tube bundle, and the orifices on each jet cooling tube are provided according to the arrangement of tube bundle. Thus, the heat transfer performance of jet impingement type shell and tube heat exchanger is remarkably enhanced.

Abstract: An air-conditioned chair is revealed. The air-conditioned chair includes a chair and an air conditioner. The air conditioner consists of at least one first pipe and at least one second pipe. The first pipe is arranged with several vents corresponding to each of two edges on top of the chair. The vents are used to release gases for air-conditioning such as cold air. The second pipe is corresponding to a return air opening on the chair so as to recycle and reuse the gases for air-conditioning A cover is covered over the chair so as to form a small closed air-conditioned space. Thus good air-conditioning efficiency is achieved by lower energy consumption. The air-conditioned chair can be arranged at different vehicles so as to reduce vehicle power output and provide passengers greatest comfort.

Abstract: An air-conditioning clothes system used in car, which has an air-conditioning device having a cooling unit and with air-conditioning clothes to be worn by the driver and passengers. The air-conditioning clothes include, in its interior, a pipe duct having air openings. The air-conditioning device is connected through connection pipe ducts to the air-conditioning pipe duct of the clothes so that cold air is driven by a convection fan located at the cooling end of the cooling unit of the air-conditioning device. When it is hot, cool air is delivered into the air-conditioning pipe duct of the air-conditioning clothes and is blown from the air openings to the ambient environment. When it is cold, warm air produced by a heating end converted by the cooling unit and driven by the convection fan to be dispersed into the ambient environment through the air openings provided on the air-conditioning pipe duct of the clothes.
