Benefits of technology

This patented technology allows an energy management company (EMS), such as a manufacturer that produces buildings with multiple units connected through pipes, to automatically manage their environmental conditions by controlling certain parts within them based upon factors like power usage levels and weather patterns. It also includes advanced techniques like precision ventilators and intelligently adjusted fans to reduce stresses caused by changes made over large areas during winter months. Additionally, this technology uses various sensors to gather important details about indoor environments from different locations throughout its network. Overall, these technical improvements improve energy utilization and optimize occupant comfort while reducing costs associated therewith.

Problems solved by technology

This patented describes how to improve the efficiency at which houses are being built by reducing energy consumption while maintaining good health conditions during construction or maintenance tasks. By utilizing these techniques, there can be improved space management within homes that require less power than traditional methods such as heat pumps. Additionally, the use of multiple ventilators allows for precise regulation over different parts of an indoor environment. Overall, this technology helps reduce carbon emissions from fossils used for making materials and saves money compared to current ways of doing things.

Embodiment 1

[0042] Such as figure 1 As shown, the environmental control system suitable for raising pigs in a building according to the present invention includes two parts: a sub-control system and a main control system, wherein:

[0043] The sub-control system includes several floors, and each floor includes several units. Each unit is equipped with a sub-controller, an environmental parameter sensor, a wet curtain, a ventilation window and a spoiler fan. The environmental parameter sensor collects real-time environmental parameters. The curtain is installed on the side of the ventilation window, and the spoiler fan introduces fresh air into each unit to discharge dirty air; the environmental parameter sensors include high-precision temperature and humidity sensors, gas sensors, negative pressure sensors and wind speed sensors, and the high-precision temperature and humidity sensor acquisition unit Internal temperature and humidity, the gas sensor includes carbon dioxide sensor or ammon...

Embodiment 2

[0048] Such as figure 2 As shown, the control method of the environmental control system suitable for raising pigs in buildings according to the present invention comprises the following steps:

[0049] Step S1: preset target parameters: set the required environmental indicators for units with different functions; manually set the environmental indicators on the display screen, and the environmental indicators refer to the most suitable buildings for different functions and population units. The target parameter values ​​of the building environment, such as the target temperature, target negative pressure and target ventilation rate in each unit building.

[0050] The target temperature can be obtained through the algorithm of the age curve of the breeding livestock and poultry. The algorithm of the age curve of the breeding livestock and poultry: calculate the real-time target ambient temperature according to the preset age curve (set D 1 , T 1 is the first target age and ...

Embodiment 3

[0076] In the following example, there are eight floors on site, 420 fans are installed in total, and the actual commissioning time is one month:

[0077] The pigs on site are relatively young in age and are sensitive to temperature. Set α=0.6, β=0.2, the temperature adjustment weighting coefficient is heavier, and δ=1 closes the δ self-adjustment option;

[0078] Under this setting, the setting values ​​of each sub-control are as follows (setting t 1 is the end time of the last calculation period, t 2 Calculate period start time for this machine):

[0079] Δ1=0.6*T 1 +0.2*P 1

[0080] Δ2=0.6*T 2 +0.2*P 2

[0081] ...

[0082] Δn=0.6*T n +0.2*P n

[0083] (T n and P n is each unit t on site 1 ->t 2 The change value of temperature and house pressure within a time period, n is a natural number greater than or equal to 1)

[0084] Change the weighted value of each unit at t 1 ->t 2 Integral summation over time period, namely:

[0085] Process variable S=∫Δ1+∫Δ2...
