Title of Invention: Smart Energy Saving Air Conditioner

[1] The present invention relates to an intelligent energy-saving type air conditioner.

Background technique

[2] In recent years, due to the rapid development of communications, energy, transportation, power and other industries, the data transmission speed and coverage density requirements are getting higher and higher. The data processing equipment previously arranged in the large computer room is gradually moved to the outdoor cabinet or base. In the station, it is placed close to the user or terminal. On the one hand, the processing speed of modern data processing equipment is generally improved, but the power dissipated is increased and released in the form of thermal energy. On the other hand, the outdoor cabinet equipment is exposed, directly radiated by sunlight, and generates a large amount of heat. Therefore, the outdoor cabinet or base station adopts a heat-insulated housing structure to reduce the introduction of external temperature, thereby reducing the load of the air conditioner. However, when the ambient temperature is lower than the internal temperature of the cabinet or the base station, the heat inside the cabinet or the base station cannot be transmitted to the environment due to the heat insulation function of the housing, so that even at a lower temperature, the air conditioner needs to start cooling. This consumes a lot of power, which shortens the service life of the air conditioner. At the same time, the single-use air-conditioning cooling scheme will cause the temperature in the cabinet or base station to rise sharply when the air conditioner fails, causing equipment failure.

Summary of the invention

[3] An object of the present invention is to provide an intelligent energy-saving air conditioner which has a compact structure and a simple working principle, and can solve the problems of excessive energy consumption and redundant redundant standby systems existing in the prior art.

[4] The technical solution of the present invention is: an intelligent energy-saving air conditioner, comprising an air conditioner control device, the air conditioner further comprising a heat exchange circulation system and a refrigeration system respectively controlled by the control device, the control device including internal and external Temperature collection unit.

[5] A further technical solution of the present invention is: the circuits of the heat exchange circulation system and the refrigeration system are independent of each other, and are switched by the automatic control device or used at the same time, which has high reliability and saves energy. The heat exchange circulation system includes an internal heat exchanger and an external heat exchanger that are connected by a heat exchange circulation pipe system, and the refrigeration system includes an evaporator, a condenser, and a compressor that are connected through a refrigeration cycle pipe system, and the air conditioner further An internal fan shared by the internal heat exchanger and the evaporator, and an external wind shared by the external heat exchanger and the condenser Machine.

[6] The heat exchange cycle system is a gas-liquid heat exchanger heat exchange system, and the gas-liquid heat exchanger further includes a fluid drive device connected to the heat exchange cycle pipe system. The fluid drive device may be a variety of devices that can drive fluid flow, such as a magnetic pump, a vane pump, a diaphragm pump, a centrifugal pump, a rotor pump, an axial pump, or a plunger pump.

[7] The present invention can change the appearance size, the fan form, the compressor power, the fluid drive device, and the heat exchanger form according to different cold gauge specifications.

[8] A more detailed technical solution of the present invention is: the air conditioner is an integrated air conditioner, the fluid drive device and the compressor are disposed at a bottom of the air conditioner, and the outer fan is located outward in the air conditioner housing On one side, the outer heat exchanger and the condenser are located above the outer fan; the inner fan is located on an inward side of the air conditioner housing, and the inner heat exchanger and the evaporator are located below the inner fan.

[9] The air conditioner is a split type air conditioner, and the outer fan, the outer heat exchanger, the condenser, and the compressor are located in an outer unit of the air conditioner, and the outer heat exchanger and the condenser are located at an outlet of the outer fan The inner fan, the inner heat exchanger, the evaporator and the fluid drive device are located in the inner machine of the air conditioner, the inner heat exchanger and the evaporator are located under the inner fan; the heat exchange circulation pipe system and the refrigeration cycle pipe It is connected between the internal unit of the air conditioner and the external unit.

[10] In addition to the above-described integral and split forms, the present invention can also be installed in a variety of ways such as wall mounting, embedding, overhead or landing.

[11] The internal and external temperature collection comparison unit of the control device can monitor the temperature inside the cabinet and the base station and the external ambient temperature, and compare the two. When the temperature in the cabinet or the base station is higher than the external ambient temperature and reaches the set start temperature of the heat exchange cycle system, the control device causes the heat exchange cycle system to start, the fluid drive device of the present invention starts to operate, and the fan starts to operate. At this point the refrigeration system is at a standstill. When the heat exchange cycle system is started, when the temperature in the cabinet or base station collected by the collection unit is still higher than the startup temperature set by the refrigeration system, the control device controls the refrigeration system to start; if the temperature outside the cabinet is still lower than the cabinet The internal temperature, the heat exchange cycle system continues to work, and the two systems operate simultaneously. When the ambient temperature outside the cabinet or base station is higher than the internal temperature, and the internal temperature is higher than the set cooling system startup temperature, the control device controls the operation of the refrigeration system, and the heat exchange cycle system is in a stopped state. When one of the heat exchange cycle system or the refrigeration system fails, the other system can be started under the control of the control unit.

[12] The advantages of the invention are: [13] 1. In the case where the ambient temperature is lower than the internal temperature of the cabinet or the base station, but still needs to be cooled by the steam compressor refrigeration device, the heat is exchanged through the heat exchanger device, and the air inside and outside the cabinet or the base station is 1 In the case of 00% isolation, cooling is achieved by using fans and fluid drives and heat exchangers, and the energy consumption is reduced by 70<3⁄4 compared to the steam compressor unit.

[14] 2. Compared with the fan, the ambient air is directly ventilated and cooled, the invention can prevent the air vapor, dust and other impurities in the environment from polluting the air inside the cabinet or the base station, and avoid the polluted air outside the cabinet entering the cabinet during direct ventilation. Causes the components inside the cabinet to be contaminated.

The cooled coolant enters the inner heat exchanger 21 of the inner circulation. Since the air temperature of the inner circulation is higher than the temperature of the inflowing coolant, the coolant is heated, flows to the outer heat exchanger 22 of the outer circulation by the fluid driving means 23, and is cooled, thus repeating the cycle. The heat of the inner circulation side air can be transferred to the outer circulation side air by the flowing coolant, thereby achieving temperature transfer in the case where the air inside the cabinet is completely isolated.
