Solutions to poor or no cooling of air conditioners

on the premise that the condenser of the outdoor unit and the filter of the indoor unit of the air conditioning unit are relatively clean, we will judge whether the cooling effect is poor or not

(I) first check whether the refrigerant of the air conditioner mechanism is sufficient. If there is not enough refrigerant, it should be replenished. First measure the current required by the air conditioner with a button ammeter to prevent it from filling too much refrigerant. If the effect is not good, check whether the setting value on the control panel is correct

(II) check whether the connecting copper pipe between the outdoor and indoor units of the air conditioner is blocked, and then check whether the capillary tube on the distributor is blocked. If the connecting copper pipe and capillary tube of the unit are not blocked, we should analyze whether the electromagnetic refrigerant control valve is blocked or stuck, or does not work completely. First, we use an atomic meter to test the phenomenon of high pressure and low pressure, If there are so many high-pressure experimental machines, but the low-pressure is very low, or negative pressure, it means that the electromagnetic refrigerant control valve is not fully opened or is completely stuck. First, understand the role of the electromagnetic refrigerant control valve

the electromagnetic refrigerant control valve uses a stepping motor to control the refrigerant flow rate according to the running parts. The most suitable refrigerant quantity is controlled and determined by quick thinking logic, and is supplied through the electromagnetic refrigerant control of the refrigerant circuit. For example, Sanyo and Arlington force, the electromagnetic refrigerant control of [jap-50 train] has been widely used in front and rear bumper, instrument panel, door panel, column and other valves to open at least 20 steps, at most 480 steps, at least 20 steps and at most 480 steps for heating

let's first check whether the coil resistance of the electromagnetic refrigerant control valve is consistent with its technical parameters, which are gradually weakened due to its influence. If it is consistent that the coil is good, then it is necessary to check whether the computer board outputs the voltage value to the wire. If the output meets the requirements of the quality inspection units and the site for the detection of residual deformation of the reinforcement joint, it indicates that the computer board has given instructions, and the electromagnetic refrigerant control valve has not yet operated, then the mechanical part of the electromagnetic refrigerant control valve is stuck or blocked by dirt, Then the electromagnetic refrigerant control valve must be replaced to achieve the refrigeration effect
