16322 results about "Air conditioning" patented technology

Air conditioning (often referred to as AC, A/C, or air con) is the process of removing heat and moisture from the interior of an occupied space to improve the comfort of occupants. Air conditioning can be used in both domestic and commercial environments. This process is most commonly used to achieve a more comfortable interior environment, typically for humans and other animals; however, air conditioning is also used to cool and dehumidify rooms filled with heat-producing electronic devices, such as computer servers, power amplifiers, and to display and store some delicate products, such as artwork.

Ventilation device

The invention discloses a ventilation device, which aims to solve the problem that the conventional ventilation device does not have an air adjusting function. The device comprises a pedestal, a high-speed air blower and an annular ejector, wherein the high-speed air blower is arranged at the bottom of the pedestal; the annular ejector is arranged at an air outlet of the high-speed air blower and is fixed on the pedestal; and the air inlet or the air outlet of the high-speed air blower is provided with a vapor generator which is fixed on the pedestal for producing water vapor. In the ventilation device, the water vapor is produced through the vapor generator and is ejected through an atomization nozzle at a high speed to produce fog of smaller granularity, so that a hot air flow can more easily absorb the latent heat of vaporization, and the ventilation device has a humidification effect and a heat absorption and temperature reduction effect on a large amount of hot air sucked by the annular nozzle, and brings comfortable cool air similar to air on the shore of a lake or a sea to the surrounding environment. In the ventilation device, an external circulating device is not required to be mounted, so the cost is low; the space is not required to be closed, so that air convection is guaranteed; and the ventilation device is more energy-saving in the same temperature reduction range compared with a fan and an air conditioner, and can be used conveniently and safely.

Air-conditioning system, air-conditioner and refrigerant recycling control method

The invention discloses an air-conditioning system. The air-conditioning system comprises a compressor, a four-way valve, an indoor heat exchanger, an outdoor heat exchanger, a control valve and a throttling control assembly. The first end of the four-way valve is connected with the second end of the four-way valve through the outdoor heat exchanger, the throttling control assembly, the indoor heat exchanger and the control valve in sequence. The third end of the four-way valve is connected with an exhaust outlet of the compressor. The fourth end of the four-way valve is connected with an air return opening of the compressor. The throttling control assembly is used for throttling a refrigerant flowing into the indoor heat exchanger from the outdoor heat exchanger, and meanwhile controlling the opening degree of a flow path between the outdoor heat exchanger and the indoor heat exchanger. The invention further provides an air-conditioner and a refrigerant recycling control method. According to the air-conditioning system, the air-conditioner and the refrigerant recycling control method, when the refrigerant is recycled, the throttling control assembly can be closed directly so as to recycle the refrigerant, the control valve is closed to achieve automatic recycling of the refrigerant when refrigerant recycling is completed, and thus the refrigerant recycling cost can be reduced.

Adjusting method and adjusting device of electronic expansion valve for air conditioning unit

The invention provides an adjusting method of an electronic expansion valve for an air conditioning unit. The method comprises the steps of detecting indoor environment temperature Ti, outdoor environment temperature To and compressor running frequency f when the air conditioning unit is stared and runs, determining the initial opening degree P1 of the electronic expansion valve through the formula of P1= A*Ti + B*To + C*f + D, controlling the initial opening degree of the electronic expansion valve according to the P1, detecting the actual exhaust gas temperature T of a compressor after the air conditioning unit runs stably, enabling the electronic expansion valve to maintain a current opening degree state when the T is in an optimum target exhaust gas temperature range, reducing the opening degree of the electronic expansion valve when the T is lower than the lower limiting value of the optimum target exhaust gas temperature range, increasing the opening degree of the electronic expansion valve when the T is higher than the upper limiting value of the optimum target exhaust gas temperature range, and returning to a former step. The adjusting method reduces the time needed for adjusting the electronic expansion valve, and improves the reliability of the running of the air conditioning unit. The invention further provides an adjusting device of the electronic expansion valve for the air conditioning unit.

Intelligent household air-conditioning system with linkage function

The invention discloses an intelligent household air-conditioning system with a linkage function. The system comprises a range finding apparatus used for detecting signal intensity information of terminal equipment carried by a user and selecting whether sending a first air-conditioning linkage command to an intelligent household server or not according to the signal intensity information, the intelligent household server used for sending a door and window closing command to an electric door and window apparatus according to the first air-conditioning linkage command and sending an air-conditioning starting command to an air-conditioning apparatus further according to the first air-conditioning linkage command, the electric door and window apparatus used for executing a closing operation of a door and a window according to the door and window closing command, and the air-conditioning apparatus used for starting an air-conditioner according to the air-conditioning starting command. According to the invention, when a user gets home, the air-conditioning system can automatically start the air-conditioner in advance and close the door and the window simultaneously, temperature, humidity, wind speed and the like in a room can be automatically adjusted, and the air-conditioner can be automatically shut down after leaving of the user.
