An air conditioning system, comprising an outdoor unit and an indoor heat exchange mechanism. The indoor heat exchange mechanism comprises an air conditioner indoor unit and a first heat exchange mechanism used for at least one among water cooling, water heating and space heating. The present air conditioning system integrates various functions into one, such as air-conditioning refrigeration, air-conditioning heating, producing household cold water, producing household hot water, and home heating by means of connecting indoor units for cooling and heating, a water cooling mechanism, a water heating mechanism and a device for floor heating located indoors to one outdoor unit. Moreover, the system directly utilizes high-temperature refrigerant to heat water for floor heating.

Air conditioning system

A continuous heating control system and method, and an air-conditioning device. The system includes a defrosting solenoid valve () arranged on a bypass pipeline, wherein one end of the bypass pipeline is connected to an oil separator (), and the other end of the bypass pipeline is connected to an outdoor heat exchanger (); and a heating structure which is arranged at the bottom of a gas separator () and used for heating the gas separator ().

Continuous heating control system and method, and air-conditioning device

A control method, a control device for starting an air conditioner, a storage medium, and an air conditioner are disclosed. The method includes the step of acquiring current temperature variation information of a weather in an environment of the air conditioner and current startup parameters of the air conditioner. The method further includes the step of controlling operation parameters of the air conditioner according to the current temperature variation information and the current startup parameters of the air conditioner.

Control method, control device for starting air conditioner, storage medium and air conditioner

An air conditioning system, including a compressor, two outdoor heat exchange units, a liquid pipe used for communicating with indoor units, a high-pressure gas tube and a low-pressure gas tube; the air conditioning system further includes a valve assembly. One outdoor heat exchange unit has a first state in which one end thereof communicates with the high-pressure gas tube and another end thereof communicates with the liquid pipe, and has a second state in which one end thereof communicates with the low-pressure gas tube and the other end thereof communicates with the liquid pipe. Further disclosed is a control method for the air conditioning system.

Air conditioning system and control method for air conditioning system

A heat pump system and a control method therefor. The heat pump system includes a compressor; an indoor heal exchanger; an outdoor heat exchanger, including a first heat exchange portion and a second heat exchange portion, wherein a flow path switching device is provided between the first heat exchange portion and the second heat exchange portion to disconnect or communicate the first heat exchange portion and the second heat exchange portion; a first four-way valve; and a second four-way valve, configured to enable a high-temperature refrigerant to be input into the first heat exchange portion in a heating mode, so as to enable the heat pump system to operate in a heating and deicing mode.

Heat pump system and control method therefor

An air-conditioner outdoor unit and a control method for a fan () of an air-conditioner outdoor unit; the air-conditioner outdoor unit of the present invention comprises a fan () and a deflector ring () that is sleeved on the outside of a vane () of the fan (); further comprised are a vane stopping device (), a wind speed measuring device (), and a control system. The vane stopping device () is disposed on the deflector ring (), is connected to the control system, and may cause a vane () that is passively rotating to stop rotating; the wind speed measuring device () is connected to the control system, and is used for detecting the wind speed flowing through the vane (), the wind speed comprising a wind speed value and a wind speed direction; the control system controls the vane stopping device () to start and shut down according to the wind speed that is detected by the wind speed measuring device (), and controls actual start-up frequency of the fan () according to the wind speed that is detected by the wind speed measuring device (). The air-conditioner outdoor unit and the control method for the fan () of the air-conditioner outdoor unit may compensate the rotational speed of the fan (), and ensure the start-up success rate of the fan ().
