7results about How to "Improve cooling and heating effect" patented technology

The present disclosure relates to a compressor and a variable capacity mechanism fault detection method, device and system thereof, and a medium. The compressor variable capacity mechanism fault detection method comprises: controlling the compressor to start and frequency up to a test frequency according to a first mode, obtaining a reference current after the compressor is stably running, the first mode being a double-cylinder mode or a single-cylinder mode; sending a first switching instruction to the compressor, and controlling the compressor to switch from the first mode to a second mode, wherein the second mode is a reverse mode of the first mode; obtaining a first current change value within a predetermined time period after the first switching instruction is sent; and determining whether the variable capacity mechanism is faulty according to whether the first current change value is greater than a predetermined threshold. The present disclosure can quickly and accurately determine whether the variable capacity electromagnetic valve and the sliding vane mechanism are normally actuated during the starting stage of the compressor, thereby improving the refrigeration / heating effect and improving the system energy efficiency.

This invention discloses an air conditioner-water heater main unit fusion body with a compressor arranged in a tiered manner in the negative pressure chamber ventilation blind zone. A heat exchanger is set inside the fusion body shell to form a negative pressure chamber, and the area of ​​the negative pressure chamber near the back plate is a ventilation blind zone. The high-power, heavy, and noisy air conditioner compressor and air source water heater compressor are arranged in a tiered manner on the base plate corresponding to the ventilation blind zone, sharing the negative pressure chamber space resources on the base plate. This significantly lowers the structural center of gravity of the air conditioner-water heater main unit fusion body, suppresses the structural resonance of the main unit caused by the compressor operation, and creates the conditions and advantages for the fusion of the air source water heater main unit and the air conditioner main unit.
