The invention relates to a fan filter unit with fixed surface air speed and controllable area. The fan filter unit comprises a device casing, the bottom of the device casing is provided with an air outlet, the top of the device casing is provided with a circular air suction port, a fan is arranged below the circular air suction port, a filter is arranged below the fan, and an air speed sensor is arranged at the center below the filter and is connected with a controller through a lead, wherein the controller is arranged on the top of the device casing and used for controlling rotation speed of the fan. The fan filter unit breaks through the conventional method of controlling air quantity by changing air speed via area fixing type, senses and monitors the air speed of the air outlet by means of the sensor and timely feeds the air speed back to the controller, and the controller can immediately transmits signals to enable rotary shafts on two sides of a box to rotate in or out to adjust the area of a windward side, so that air quantity can be changed, air speed can be stabilized, and airflow distribution can be constant.

The invention discloses an air conditioner control method, a terminal, an air conditioner and a computer readable storage medium. The air conditioner control method comprises the steps of receiving environmental parameters of air supply areas of air outlets of the air conditioner detected by an infrared sensor, determining a target air supply area with the environmental parameter being located ina preset numerical zone from the air supply areas, and adjusting the air supply velocity of the air outlet corresponding to the target air supply area according to a logical relationship between a preset environmental parameter and the air velocity. According to the logical relationship between the environmental parameter of each air supply area and the air velocity, the air velocity of the corresponding air outlet is intelligently controlled, so that the problem that in the prior art, during a cooling or heating process of the air conditioner, in order to achieve the aim of cooling or heating, the air velocity of the air outlets is unchanged, so that the human comfort experience is influenced is effectively solved; and in addition, air outlet modes of other air outlets with the environmental parameters being not located in the preset numerical zone are unchanged, and the user experience is improved while a cooling or heating function is realized.

The invention provides a high-chromium wear resistant casting iron part rotary spraying quenching process. The high-chromium wear resistant casting iron part rotary spraying quenching process comprises the following steps that the first step, a casting workpiece to be quenched is placed inside a high-temperature furnace to be heated to raise the temperature, and heat preservation is performed fora while; the second step, the high-temperature casting workpiece in the first step is placed on a rotary workbench; the third step, the rotary workbench is started, and the casting workpiece is drivenby the rotary workbench to rotate at high speed; the fourth step, spraying devices located on the side surfaces of the rotary workbench are started, and water is supplied for the spraying devices through a water supplying device and water supplying pipes; the fifth step, the water after atomization is sprayed to the surface of the rotating casting workpiece through the spraying devices, and rapidcooling treatment is performed on the casting workpiece; the sixth step, the casting workpiece after rapid cooling treatment in the fifth step is transferred onto an air cooling rack; the seventh step, an air cooling device is started, and the casting workpiece after rapid cooling treatment is cooled through the air cooling device. By means of the high-chromium wear resistant casting iron part rotary spraying quenching process, the surface wear resistant performance of high-chromium casting parts is greatly enhanced.

The invention discloses an air speed control device used in a plastic cracking test of concrete. The device comprises an air source, wherein the air source is connected with a return pipeline for uniformly mixing air; the return pipeline is provided with more than one return pipeline air outlet; and the return pipeline air outlet is provided with a plurality of air outlet holes which are formed uniformly and is connected with an air outlet pipe (6). The air speed at the air outlet is varied by varying the model number of a centrifugal blast blower and the angle between the upper surface of the outlet of the air outlet pipe and a horizontal plane, so that effective control over the air speed is realized, the problems of instable and non-uniform air speed caused by a fan are solved and the accuracy and repeatability of a test result are enhanced. The air speed control device can be used in the plastic cracking test of the concrete and a water evaporation test of the concrete in a plastic state, such as the effects of different curing modes and curing agents on the water evaporation of the concrete.

The invention discloses an air blower support used for automobile testing. The air blower support comprises a square base and two balance adjusting structures, two side frames are mounted on the base and are parallel to each other, a groove is formed in each side strip, two arc-shaped plates are mounted between the side frames, small rollers are connected on the end portions of two ends of the arc-shaped plates, crescent grooves are formed in the base, the bottoms of the arc-shaped plates are slidably arranged in the crescent grooves through rollers, and the balance adjusting structures are arranged between the crescent grooves and the arc-shaped plates. The balance adjusting structures sequentially eliminate undesirable effect generated by vibration of the left end and the right end of an air blower, and sudden stress generated when the air blower is just started can be eliminated when the small rollers slide back and forth in the grooves, so that the arc-shaped plates and the air blower are enabled to maintain balance in the whole process from the time when the air blower starts to work to the time when the same stops working, and an air source capable of stably pushing on the ground is formed; the air blower is adjustable in power and changeable in air speed.
