This utility model discloses a heating furnace device with a heat treatment atmosphere control structure, belonging to the technical field of heating furnaces. It includes a combustion structure comprising a fuel tank and a burner. A furnace body structure is installed on top of the fuel tank, including a furnace wall and a cover plate. An atmosphere control inlet structure is connected to the outer wall of the fuel tank, comprising an inlet pipe and a conversion box. One end of the inlet pipe is connected to a diffusion structure. A heating structure is installed inside the fuel tank, including an airflow equalization plate, a heater, and vortex guide ribs. A detection component is installed on one side of the furnace wall, comprising a slide rail, a slider, and a gas concentration detector. By setting a diffusion structure on the outside of the furnace wall, the gas is transported and diffused in a laminar flow from bottom to top, enhancing the uniformity of gas flow and improving the heating effect.

This invention relates to the field of multi-split air conditioning system technology, specifically to a disturbance control method for the outer loop electronic expansion valve of an air conditioning system. The problem this invention addresses is how to actively eliminate oil and refrigerant blockage and reduce exhaust temperature during defrosting or oil return processes through forced disturbance control of the outer loop electronic expansion valve. To solve this problem, this invention provides a control method comprising: acquiring the operating status parameters of the air conditioning system; determining whether the air conditioning system has triggered a disturbance program based on the status parameters; correcting the reference setting based on the exhaust temperature, compressor return superheat, and oil separator return oil temperature during the execution of the disturbance mode; determining whether to exit the disturbance program based on the exhaust temperature and the execution duration of the disturbance program during defrosting and oil return modes; and automatically exiting the disturbance program when the air conditioning system exits the defrosting or oil return mode.

The application provides a heat exchange structure, an air conditioner and a control method. The heat exchange structure comprises: an outdoor unit arranged outdoors, the outdoor unit comprising a compressor, a defrosting pipeline arranged on the compressor; an outdoor heat exchanger arranged in the outdoor unit, the outdoor heat exchanger being connected with the defrosting pipeline, the defrosting pipeline being connected with the compressor, so that fluid in the compressor flows into the outdoor heat exchanger; a heating pipeline, one end of the heating pipeline being connected with the outdoor heat exchanger, the other end of the heating pipeline being connected with the compressor, so that fluid in the outdoor heat exchanger flows into the compressor, the heating pipeline being provided with a heating component for heating fluid; the heating pipeline is provided with a gas-liquid separator for separating gas and liquid; a heat exchange device, the heat exchange device being connected with the heating pipeline and the defrosting pipeline, so as to exchange heat between fluid in the heating pipeline and fluid in the defrosting pipeline. The heat exchange structure solves the problem of liquid accumulation in the gas-liquid separator, improves the amount of refrigerant circulation during heating, reduces the defrosting frequency of the unit, and improves the heating use comfort.
