Water supply temperature regulating method and device of heat pump water heater

The invention discloses an air valve control method and an air conditioner system. The air conditioner system comprises an outdoor unit and a fan cover, and the fan cover is arranged on the outdoor unit and provided with an air valve. The air valve control method comprises the steps that when the air conditioner system operates, the air valve is controlled to be opened; the opening degree of the air valve is adjusted according to the rotation speed of a fan of the outdoor unit and the preset rotation speed of the fan; and/or the opening degree of the air valve is adjusted according to the system pressure and the target system pressure of the air conditioner system and the rotation speed of the fan. The air valve can adjust the air volume so as to adjust the heat dissipating capacity of theoutdoor unit. The opening degree of the air valve is adjusted according to the rotation speed of the fan, the fan can keep the better working efficiency, energy consumption of the fan is advantageously reduced, and the service life of the fan is prolonged. The opening degree of the air valve is adjusted according to the system pressure, the target system pressure and the rotation speed of the fan, the heat dissipating capacity of the outdoor unit can be adjusted, and accordingly the system pressure is controlled to meet the refrigeration or heating demand of the air conditioner system under the low temperature environment, and the application range of the air conditioner system is expanded.

The invention discloses a control method for an air conditioner. The method comprises the following steps of detecting whether or not the air conditioner meets a humidification condition; if yes, adjusting an air guide plate of a fresh air port to deflect towards the direction of an air outlet. The invention further discloses the air conditioner and a computer readable storage medium. According tothe control method, by adjusting the air guide plate of the fresh air port, air discharged from the fresh air port is mixed with air discharged from the air outlet, and the uniform distribution of indoor environmental humidity is achieved.

An outdoor unit (100) has a housing (1), a heat exchanger (10), an electrical component box (5), a substrate (4), and a heat dissipation section (3) having a plurality of fins and configured so that first end sections (33) of the fins, which are located on the windward side of air passages (30) formed between adjacent fins, face the electrical component box (5). In a top view of the heat dissipation section (3) and the electrical component box (5), there are formed between the electrical component box (5) and the first end sections (33) a first gap (CL1) which has a first width (W1) and a second gap (CL2) which is located closer to a rear surface panel (1b) than the first gap (CL1) and which has a second width (W2) greater than the first width (W1).

The invention provides a fan assembly and a multi-split system. The multi-split system comprises a plurality of fan assemblies, and each fan assembly comprises a fan body, an air hood and at least oneair guiding part. Each air hood surrounds the air outlet side of the corresponding fan body to form an air duct in the air hood. Each air guiding part divides the corresponding air duct into a firstair section and a second air section, each first air section is close to the corresponding fan body, and each air guiding part is rotationally arranged on the corresponding air hood to open or close the corresponding air duct. The air guiding parts close the corresponding air ducts when the corresponding fan bodies do not rotate and exhaust air, and each air guiding part has a minimum opening angle greater than zero degree with the air outlet direction of the corresponding fan body. According to the technical scheme, due to the arrangement of the air guiding parts, airflow can be effectively blocked, so that the purpose of self-adaptive adjustment of an air valve according to the air volume of an external fan is realized, the fan assemblies can be ensured to realize ultra-small air volumeadjustment, and the minimum opening angle is set so that a gap can be left between each air guiding part and the corresponding fan body to prevent the air guiding part and the fan body from being stuck.
