What is the acceptable range for maintaining dry-bulb temperatures according to HVAC standards?

The acceptable range for maintaining dry-bulb temperatures according to HVAC standards is set at ±1°C. This precision is crucial for environments like laboratories and animal care facilities where temperature control is essential for the welfare of the animals and the integrity of experimental conditions.

Maintaining temperatures within this narrow range helps ensure that both the physiological needs of the animals are met and that any scientific experiments remain valid, avoiding temperature variations that could impact results.

Wider allowable ranges, such as ±3°C or ±5°C, may not provide the necessary control needed in sensitive environments, as these could lead to thermal stress on animals or interfere with experimental conditions. Similarly, a tighter range of ±0.5°C, while beneficial for highly sensitive applications, is often impractical and not a standard requirement in typical HVAC guidelines. Thus, ±1°C strikes a balance between effective temperature control and operational feasibility in specialized settings.
