The heat pump type all-in-one machine disclosed by the invention has super high dampness removing capacity, has a heat recovering function, has a function of preheating fresh air, and has high functional integration. Through the adoption of the heat pump type all-in-one machine disclosed by the invention, the air dampness is reduced, the cleaning degree of the air is increased, and particularly the effects of the heat pump type all-in-one machine on air in southern cities of China are obvious.

A cogeneration system includes an engine, a generator connected to an output shaft of the engine to generate electricity, a heat pump type air conditioner, which uses the electricity generated from the generator, and includes a compressor, a directional valve, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger, a fluid-heating heat exchanger to heat a fluid, and a waste heat recovering means to supply waste heat of the engine to the heat pump type air conditioner or to the fluid-heating heat exchanger, so that the system exhibits a high energy efficiency.

An air-outlet mode selecting device includes first and second rotary doors. Each of the first and second rotary doors has rotary shafts separated from each other in an axial direction of the rotary shafts, an outer peripheral door surface that is provided at a position separated radial outward from the center line of the rotary shafts and is turned with the rotary shafts, and left and right side plates for connecting both ends in the axial direction of the outer peripheral surface and the rotary shafts. One of the first and second rotary doors opens and closes a specified opening among three openings and other rotary door opens and closes the remaining two openings among the three openings. Accordingly, door operation force and air flow resistance can be effectively reduced, and the size of the air-outlet mode selecting device can be effectively reduced.

Disclosed is an apparatus and method for controlling an air cleaning. The apparatus includes an air cleaning element, an AC high-voltage generator and a control unit. The air cleaning element generates negative ions and ozone using plasma discharge, and cleans indoor air using the negative ions and ozone. The AC high-voltage generator generates an AC high-voltage, and applies the AC high-voltage to the air cleaning element. The control unit varies at least one of the AC voltage and AC frequency applied to the air cleaning element by the AC high-voltage generator depending on a state of indoor air being cleaned using the air cleaning element. Therefore, it is possible to effectively generate negative ions while minimizing ozone generation to an acceptable level depending on a state of indoor air, thereby increasing air cleaning performance so as to sterilize and clean contaminants more efficiently.

By disposing external straps 36 to 38 which are passed through a tubular member 34 which passes through an air bag 21 in a tunnel-like fashion to open in side surfaces of the air bag 21 are disposed on an outer circumference of the air bag 21 and controlling the deployment shape of the air bag 21 by the external straps 36 to 38 so disposed, the occupant restraining performance of the air bag can effectively be enhanced.

The invention discloses a static-suction-type range hood fan volute. The range hood fan volute is provided with a front cover plate, a rear cover plate and an annular middle shell connected with the front cover plate and the rear cover plate, wherein the front cover plate and the rear cover plate are respectively provided with a front air inlet and a rear air inlet, and the projection of the center of circle of the front air inlet on a plane in which the rear cover plate is positioned is coincided with the center of circle of the rear air inlet; and the middle shell at a volute tongue is of an asymmetric structure and is used for connecting the front cover plate with the rear cover plate in a continuous smooth-transitional manner, and the border outlines of the front side and rear side ofthe middle shell is optimized. The static-suction-type range hood fan volute provided by the invention has the advantages that the lateral dimension of the volute is compressed, the limitation to thelateral dimension of a range hood is overcome, and the noise is obviously reduced; and proven by repeated comparison tests, the optimized performance index can be as follows: when the air quantity is15m<3> / min and the wind pressure is 320 Pa, the noise is only 48dB.

A method is provided for controlling an external control type fan clutch. The method controls the On / Off of an electromagnet-activated valve for an oil feed adjusting hole. The method uses a PID control on the basis of radiator cooling liquid temperature, fan speed, transmission oil temperature, vehicle speed, engine speed, compressor pressure of an air conditioner, and an On / Off signal of the air conditioner. Individual gains of the PID control are determined by a gain matrix containing the optimum fan speed demanded by the engine, the actual metered fan speed, and the engine speed. The PID control is made on the basis of the gains to that a control signal is outputted. The control method can improve mileage, raise the cooling efficiency of an air conditioner and suppress fan noise.
