The invention relates to a machine room temperature control system, in particular to a control method of an evaporative machine room air energy-saving device.
Background
The low-noise air energy-saving device for the machine room is provided by the prior invention, wherein the air energy-saving device for the machine room is characterized in that the indoor temperature is required to be kept between 20 ℃ and 25 ℃, the air inside and outside the machine room is isolated, the indoor hot air is sent into an outdoor heat exchanger through a pipeline by a fan, the cooled air is sent back into the room through the pipeline, namely, the energy of the outdoor cold air is used for reducing the temperature of the indoor hot air, the purpose of saving the power consumption of an air conditioner is achieved, when the outdoor air temperature is between 20 ℃ and 26 ℃, the energy-saving device and the air conditioner work together in an energy-saving mode, and when the outdoor air temperature is reduced to below 20 ℃, the air conditioner stops working in a high-efficiency energy-saving mode. When the outdoor air temperature reaches above 26 ℃, the energy-saving device cannot work and can only work independently by the original air conditioner to enter a conventional energy consumption state, and the power consumption of the air conditioner accounts for 40-45% of the total power consumption of the machine room. When the outdoor air temperature reaches above 36 ℃, the efficiency of the air conditioner is reduced, the load is too heavy, and the air conditioner is difficult to work adequately.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a control method of an evaporative machine room air energy-saving device, which can be suitable for higher outdoor air temperature, and the invention utilizes the principle of water evaporation and heat absorption to reduce the temperature of a heat exchanger to t-delta t, wherein the delta t is approximately equal to 10-15 ℃, and the maximum use temperature can reach 36 ℃. When the outdoor air temperature reaches 36 ℃, the evaporative heat exchanger stops the internal circulation, the external circulation continues to work, and cold air is directly blown to the outdoor unit of the air conditioner. When the outdoor air temperature is below 30 ℃, the air conditioner stops working and is in a high-efficiency energy-saving mode, and 70% of electric energy can be saved.
The invention is realized by the method, which comprises an outdoor temperature sensor, an indoor temperature sensor, an automatic controller, an air outlet, a pipeline, an internal circulation fan, an evaporative heat exchanger, an external circulation fan, an air inlet and a partition, and is characterized in that the outdoor temperature sensor and the indoor temperature sensor are respectively connected with the automatic controller by wires, the automatic controller is respectively connected with a frequency modulator, the internal circulation fan, a data output display device, the external circulation fan and a water pump by wires to form an automatic control system, and the automatic control system controls the internal circulation air circulation system, the water pump and the external circulation air circulation system. The air outlet, the internal circulation fan, the evaporative heat exchanger, the air inlet and the ventilation pipeline of 3 sections or N sections are sequentially connected to form an indoor air circulation system, and indoor hot air is cooled by heat exchange circulation. The filter screen, the wet curtain, the evaporative heat exchanger and the external circulating fan form an outdoor air circulation system, so that the outdoor air cools the indoor air in the evaporative heat exchanger. Air conditioner and air conditioner are installed in machine room
The electronic equipment cabinet is characterized in that an air outlet is arranged above an air outlet of the electronic equipment cabinet, a partition is arranged beside the air outlet to gather hot air around the air outlet, the air outlet is connected with an internal circulation fan through a pipeline, the internal circulation fan conveys indoor hotter air to a heat exchanger for cooling through the pipeline, the heat exchanger is connected with an air inlet through the pipeline, and the cooled air is returned to the room. The machine room air conditioner system is independent, and the automatic control system is not connected with the air conditioner, so that the work of the air conditioner is not affected. Air in the machine room is isolated from air outside, and gas exchange does not occur, so that the problem of air dust removal does not need to be considered. The outdoor temperature sensor and the indoor temperature sensor transmit signals to the automatic controller through wires respectively, and the automatic controller controls the frequency modulator, the internal circulation fan, the water pump and the external circulation fan through wires and outputs data for display. When the outdoor air temperature rises to 20 ℃, the inner circulating fan and the outer circulating fan work simultaneously, the temperature in the machine room is maintained below 24 ℃, and the air conditioner is not started, thus the air conditioner belongs to an efficient energy-saving mode. When the outdoor temperature continues to rise, the indoor temperature also rises along with the rise, when the indoor temperature reaches 24 ℃, the water pump starts to work, the evaporative heat exchanger starts to play a role, and the indoor temperature drops below 24 ℃, so that the air conditioner is not started at the moment, and the air conditioner belongs to a high-efficiency energy-saving mode. When the outdoor air temperature rises to 33 ℃, the indoor air temperature rises to 25 ℃, the air conditioner starts to work, and the inner circulating fan and the outer circulating fan work simultaneously, and the air conditioner belongs to an energy-saving mode. When the outdoor air temperature rises to 36 ℃, the internal circulation fan stops working, the water pump and the external circulation fan continue to operate, the externally circulated cool air is directly blown to the outdoor unit of the air conditioner, the booster air conditioner works, and the air conditioner enters a normal working mode. In practical use, the sun exposure should be avoided so as not to affect the use effect.
The beneficial effects of the invention are as follows: when the outdoor air temperature is below 20 ℃, the energy of the outdoor cold air is utilized to reduce the temperature of the indoor hot air, only the fan works at the moment, and the air conditioner does not work, thus the air conditioner belongs to a high-efficiency energy-saving mode. When the outdoor temperature is 20-30 ℃, the evaporative heat exchanger plays a role, and the two fans and the water pump work simultaneously, and the air conditioner does not work, so that the air conditioner also belongs to a high-efficiency energy-saving mode. When the outdoor temperature is 30-33 ℃, the fan, the water pump and the air conditioner work simultaneously, and the energy-saving mode work is realized. When the outdoor air temperature is above 36 ℃, the internal circulation fan stops working, and the water pump and the external circulation fan assist air conditioner work, which belongs to the normal mode work. Before entering the normal mode, the power consumption of the internal circulation fan, the water pump and the external circulation fan is only 30% of that of the air conditioner, so that the energy is saved at the moment, and more than 70% of electricity can be saved. . After entering the normal mode, the evaporative heat exchanger assists the air conditioner to cool, thereby increasing the capacity of resisting high temperature, and reducing the burden of the air conditioner, which is also beneficial to cooling the machine room. 1.5 liters of water is consumed per 1 kilowatt hour of power saving, which is also reasonable in economic aspect.
