Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a control method of a machine room air conditioner, which is provided with a fresh air module and a refrigeration module and at least has a fresh air function and a refrigeration function.
As shown in fig. 1, the control method of the air conditioner in the machine room comprises the following steps:
step S101: the outdoor temperature, the indoor temperature and the set temperature are obtained, and the set temperature, the outdoor temperature and the indoor temperature are compared.
Step S102: and generating an instruction for controlling the operation of the fresh air module and the refrigeration module in the machine room air conditioner according to the comparison result of the set temperature, the outdoor temperature and the indoor temperature.
If the outdoor temperature is judged to be larger than the indoor temperature and larger than the set temperature, an instruction for controlling the refrigeration module to be independently started is generated, and the machine room air conditioner is controlled to independently start the refrigeration mode. If the indoor temperature is larger than the set temperature and is larger than or equal to the outdoor temperature, an instruction for simultaneously starting the fresh air module and the refrigeration module is generated, and the machine room air conditioner is controlled to simultaneously start the fresh air mode and the refrigeration mode. If the set temperature is judged to be larger than the outdoor temperature, an instruction for controlling the fresh air module to be independently started is generated, and the fresh air mode is independently started.
In this embodiment, this computer lab air conditioner mainly used ensures the constancy and the cleanliness of temperature in the computer lab. In the working process, the machine room air conditioner acquires the outdoor temperature Tw, the indoor temperature Tr and the set temperature Ts through the sensors. The outdoor temperature Tw, the indoor temperature Tr, and the set temperature Ts are compared.
And if the outdoor temperature is higher than the indoor temperature, the refrigeration module of the air conditioner is started, and the air conditioner starts the refrigeration mode.
If the outdoor temperature Tw is larger than the indoor temperature Tr is larger than the set temperature Ts, the outdoor temperature Tw is higher, so that the indoor temperature Tr cannot be directly adjusted by outdoor air, and at the moment, an instruction for controlling the refrigeration module to be independently started is generated to control the machine room air conditioner to independently start the refrigeration mode.
If the indoor temperature Tr is judged to be larger than the set temperature Ts and is larger than or equal to the outdoor temperature Tw, the outdoor temperature Tw is lower than the indoor temperature Tr at the moment, the indoor temperature Tr can be adjusted by using outdoor air, an instruction for simultaneously starting the fresh air module and the refrigerating module is generated, the air conditioner in the machine room is controlled to simultaneously start the fresh air mode and the refrigerating mode, the indoor temperature Tr is quickly reduced, the acting dependence on the air conditioner is reduced, and then the power consumption of the air conditioner is reduced.
If the set temperature Ts is judged to be the indoor temperature Tr which is larger than the outdoor temperature Tw, an instruction for controlling the fresh air module to be independently started is generated, and the indoor temperature is finely adjusted only through the outdoor air conditioner, so that the energy consumption of the air conditioner is reduced.
The control method of the air conditioner in the machine room provided by the invention generates an instruction for controlling the operation of the fresh air module and the refrigeration module in the air conditioner in the machine room by acquiring and comparing the set temperature, the outdoor temperature and the indoor temperature, controls the refrigeration module to be independently started to adjust the indoor temperature when the outdoor temperature is higher than the indoor temperature and higher than the set temperature, controls the fresh air module and the refrigeration module to be simultaneously started when the indoor temperature is higher than the set temperature and higher than the outdoor temperature, adjusts the indoor temperature by utilizing the outdoor air, so as to quickly reduce the indoor temperature, simultaneously reduce the dependence on the air conditioner for work and further reduce the power consumption of the air conditioner, and independently starts the fresh air module when the set temperature is judged to be the indoor temperature and higher than the outdoor temperature, only utilizes the fresh air to finely adjust the indoor temperature, thereby effectively reducing the energy consumption.
As shown in fig. 2, in the state that the refrigeration module is opened, the method includes the following steps:
step S201: the indoor temperature is compared with the set temperature.
Step S202: and judging the temperature interval in which the difference value between the indoor temperature and the set temperature is located.
Step S203: and if the difference value is judged to be in the preset temperature interval, generating an instruction for controlling the refrigeration module according to the working frequency corresponding to the temperature interval.
In order to secure the indoor temperature Tr in a state where the refrigeration module is turned on, the refrigeration module adjusts power by controlling the operating frequency of the compressor. Using the previously acquired indoor temperature Tr and the set temperature Ts, Δ T is obtained as Tr-Ts, and the temperature section in which Δ T is located is determined.
And if the difference value is judged to be in the preset temperature interval, generating an instruction for controlling the refrigeration module according to the power corresponding to the temperature interval.
For example, 0 to 5 ℃ is a preset temperature interval, if the judgment result shows that the temperature is more than or equal to 5 ℃ and less than or equal to delta T, the fresh air module and the refrigeration module are started at the same time, and the fresh air module and the refrigeration module work normally.
If the temperature is judged to be 0 ℃ and < delta T < 5 ℃, the refrigeration module operates at the preset low-energy-consumption frequency, and the compressor operates at the low-energy-consumption frequency.
In the process, the machine room air conditioner acquires the current indoor temperature through the sensor and judges the change trend of the current indoor temperature. If the current indoor temperature is judged and known to be increased, an instruction for increasing the power of the refrigeration module is generated, and the running frequency of the compressor is increased. And if the current indoor temperature is judged and known to be reduced, generating an instruction for maintaining the power of the refrigeration module, and keeping the current running frequency of the compressor to run until the indoor temperature Tr is equal to the set temperature Ts.
As shown in fig. 3, in the state that the fresh air module is opened, the method comprises the following steps:
step S301: and acquiring the indoor temperature again, and judging the variation trend of the acquired indoor temperature again.
Step S302: and if the temperature rise in the room is obtained again through judgment, generating an instruction for starting the refrigeration module.
Step S303: if the indoor temperature is judged to be reduced again, an instruction for reducing the power of the fresh air module is generated.
After indoor temperature Tr is equal to set temperature Ts, refrigeration module and corresponding compressor are closed, only open the new trend module, for guaranteeing indoor temperature Tr, this new trend module adjusts the air that gets into indoorly through the new trend fan. The fresh air conditioner acquires the indoor temperature again through the sensor, and judges the variation trend of the acquired indoor temperature again.
And if the temperature rise in the room is obtained again through judgment, generating an instruction for opening the refrigeration module, and adjusting the indoor temperature by using the corresponding compressor until the indoor room temperature is balanced.
If the indoor temperature is judged to be reduced, an instruction for reducing the power of the fresh air module is generated, and the rotating speed of the fresh air fan is reduced until the indoor room temperature is balanced.

If the first determining module 402 determines that the outdoor temperature Tw is greater than the indoor temperature Tr and is greater than the set temperature Ts, the outdoor temperature Tw cannot be directly used to adjust the indoor temperature Tr, and at this time, the first processing module 403 generates an instruction for controlling the cooling module to be independently turned on, so as to control the machine room air conditioner to be independently turned on in the cooling mode.
If the first judging module 402 judges that the indoor temperature Tr is larger than the set temperature Ts and is larger than or equal to the outdoor temperature Tw, the outdoor temperature Tw is lower than the indoor temperature Tr, the indoor temperature Tr can be adjusted by using outdoor air, the first processing module 403 generates an instruction for simultaneously starting the fresh air module and the refrigerating module, the air conditioner in the machine room is controlled to simultaneously start the fresh air mode and the refrigerating mode, the indoor temperature Tr is quickly reduced, the acting dependence on the air conditioner is reduced, and then the power consumption of the air conditioner is reduced.
