Designing An Air Handling Unit System For A Cattle Farm In Ulaanbaatar

Based on the information provided, it’s clear that planning to design an air handling unit (AHU) system for a cattle shed in Ulaanbaatar. This system needs to maintain a constant temperature and humidity level within specific ranges to ensure the well-being of the cattle and optimize their breeding conditions. Here’s a summary of the key factors and calculations involved in designing the Air Handling Unit System (AHU system):

In the overall air system, the air directed to each specific area or room undergoes central processing within the computer room. The equipment responsible for this air processing is known as an air handling unit or air conditioning unit. Air handling units with jet ports have fewer components and are primarily employed to introduce fresh air indoors while regulating indoor temperature and humidity levels.

YESNCER has thoroughly analyzed the factors influencing the design of the air handling unit (AHU) system for the cattle shed in Ulaanbaatar. Here’s a recap of the key details and recommendations:

1. Climate Characteristics Analysis:

Ulaanbaatar experiences long, cold winters and warm summers with temperature ranges between -28°C and 31°C.
The desired temperature range for the entire cowshed is 16-24°C.
The humidity level should be maintained at 60-70%.

2. Building Material and Structural Form:

The construction site consists of a scientific experiment station and a standard breeding plant.
The breeding plant has specific dimensions and room volumes, with details provided.

3. Cooling and Heating Capacity Calculation:

Cooling load: 819.27 kW
Heating load: 1465.05 kW

4. Air Handling Unit (AHU) Matching:

Building insulation coefficient + heat loss = 1.30
Temperature maintenance range: 17°C-38°C
Each AHU unit has a power rating of 60 kW.
