description A composite air conditioner vacuum defect checking method goes like this: 1. checking the ratio of the indoor and outdoor temperature and the temperature of the operating chamber of the whole indoor machine, 2. checking the coolant flow, operation high and low pressure and storing them in time sequence, 3. entering values of 1 into embedded function, deriving coolant and high and low operation pressure under normal operation and storing them in order, 4. comparing the normal value with the results checked out in 2, and judging whether it is in vacuum defective status. It comprises indoor and outdoor temperature sensor, indoor machine load inspecting section, flow sensor, high and low pressure sensor inspecting the operation status, and calculating, storing and judging section connected with the former two. It can prevent the damage to fittings and the lowering of system performance.
