According to the air conditioner indoor unit provided by the invention, by additionally arranging the rotatable purifying module support, the air purifying effect at the air inlet and the refrigerating and heating effects of an air conditioner are ensured while the size of the air conditioner indoor unit is not increased.

The invention relates to the technical field of air conditioners, in particular to a method for controlling the start-up of an air conditioner. The present invention aims to solve the problems of poor universality and poor user experience existing in the existing air conditioner start-up control method. For this purpose, the start-up control method of the present invention includes: obtaining the rotational speed of the internal fan; calculating the closing speed of the expansion valve according to the first fitting formula; calculating the acceleration of the external fan according to the second fitting formula; Combine the formula to calculate the frequency increase speed of the compressor in the frequency increase stage; control the expansion valve to close the valve at the valve closing speed to the target opening degree; control the external fan to increase the speed to the target speed according to the acceleration; preferably, close the expansion valve to the target speed When the opening degree is set and the speed of the outdoor fan reaches the target speed, the compressor is controlled to increase frequency according to the frequency increase speed. Through the above control method, the start-up control method of the air conditioner of the present invention can improve the universality of the air conditioner and improve the user experience.

The invention discloses an air-conditioning system, which comprises an air-conditioning casing fixedly arranged on the outer wall of the working chamber, a compressor (11), a condenser (12), and a compressor (11) fixedly arranged in the air-conditioning casing. An evaporator (13) and a throttling element (14); the air-conditioning system also includes a first air guiding channel and a second air guiding channel; the air-conditioning system also includes a heater (15) fixed in the air-conditioning housing , so that when heating, the first air guiding channel absorbs the cold air in the working room, and the cold air passes through the heater (15) to exchange heat to form hot air, and then the hot air enters the working room through the second air guiding channel for heating. The structural design of the air conditioning system also has excellent heating performance when the external ambient temperature is low, thereby ensuring the heating effect to be exerted. In addition, the present invention also discloses a mechanical device including the above-mentioned air-conditioning system.

The invention relates to a production method of a ventilating duct by using shaped hoops, which comprises the steps of (1) preparing a ventilating duct plate; (2) cutting the ventilating duct plate; and (3) bonding the ventilating duct plate to form a ventilating duct. The bonding process of the ventilating duct plate comprises the steps of: laying a lower ventilating duct plate, bonding a left ventilating duct plate and a right ventilating duct plate at two sides of the lower ventilating duct plate, bonding an upper ventilating duct plate between the left and the right ventilating duct plates, inserting a plurality of shaped hoops from the transverse two sides of the upper ventilating duct plate to tighten and surround the left and the right ventilating duct plate and the upper ventilating duct plate, tying with a tying band along the transverse direction of the respective ventilating duct plate, positioning, removing the shaped hoops, solidifying with a bonding agent, and removing the tying band. In the inventive production method, during bonding and solidifying processes, the shaped hoops are used for fixing the ventilating duct plates to prevent the ventilating duct plates from swinging, then the ventilating duct plates are tied by the tying band, and then the bonding site of the four ventilating duct plates are tightly bonded, so as to ensure leak tightness.

The invention relates to a process for making an arc combined air duct, which includes the following steps of: 1. making a duct plate; 2. cutting the duct plate; 3. bonding the duct plate. The duct plate includes the following manufacturing working procedures that: a, a fiber reinforced inorganic viscose layer is rolled on a template, then a selected thermal baffle is arranged on the fiber reinforced inorganic viscose layer, and then a fiber reinforced inorganic viscose layer is rolled on the upper surface of the thermal baffle so as to form a composite plate; b, the composite plate for prefabricating a left duct plate and a right duct plate is placed flat, solidified and shaped; c, the composite plate for prefabricating an upper duct plate and a lower right duct plate, and the template are bent to take an arc shape and then fixed on a setting device with arc grooves for solidification and shaping. The process for making the arc combined air duct has the advantages that the air duct manufactured by adopting the process can be conveniently applied to a ventilating duct with elbows, three ways or four ways to keep the ventilating duct smooth and fluent and avoid the internal airflow from being blocked so as to effectively reduce the noise and ensure the using effect, and can be simply and conveniently arranged.

The invention discloses a multiple online control method and system. The method comprises the steps that the set temperature and the indoor environment temperature of each indoor unit are obtained, and the temperature difference is calculated; the comprehensive temperature difference is calculated; a refrigeration modification value ETS / a heating modification value CTS is calculated according to the comprehensive temperature difference; and the evaporation temperature / condensation temperature is modified, and the frequency of each compressor is adjusted. According to the multiple online control method, the frequency of each compressor is adjusted according to the modified evaporation temperature / refrigeration temperature, energy is saved, and meanwhile the refrigerating / heating effect of each indoor unit can be guaranteed. When the requirement for each indoor unit is low, the frequency of the corresponding compressor is reduced, the corresponding compressor runs at the low frequency and is kept running with the low output in a low energy consumption manner, the corresponding compressor is protected against start stop, and accordingly power rise caused by start stop of the corresponding compressor is avoided. Meanwhile, the indoor units continuously run, so that the indoor temperature is maintained near the set temperature, the constant indoor temperature is achieved, a good refrigerating / heating effect is guaranteed, and the comfort degree is improved.
