二氧化碳(CO
2)是人类呼吸的副产品。每当我们呼气时,CO就被释放到我们周围的大气中。Currently, CO
2 sensors can be used to automatically control ventilation systems in buildings equipped with
Building Automation Systems (BAS). This is referred to as
Demand Control Ventilation (DCV).

能量回收通风系统

//www.diesprinter.com/雷竞技raybeknowledgebase/division-23-heating-ventilating-and-air-conditioning/23-05-00-common-work-results-for-hvac/energy-recovery-ventilation-systems
Energy recovery ventilation systems provide a controlled way of ventilating a home while minimizing energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside air being exhausted to the fresh (but cold) supply air. In the summer, the inside air cools the warmer supply air to reduce ventilation cooling costs.

Balanced ventilation systems, if properly designed and installed, neither pressurize nor depressurize a house. Rather, they introduce and exhaust approximately equal quantities of fresh outside air and polluted inside air, respectively.

排气通风系统通过减压建筑工作。By reducing the inside air pressure below the outdoor air pressure, they extract indoor air from a house while make-up air infiltrates through leaks in the building shell and through intentional, passive vents.

The decision to use whole-house ventilation is typically motivated by concerns that natural ventilation won't provide adequate air quality, even with source control by spot ventilation.

//www.diesprinter.com/雷竞技raybeknowledgebase/division-23-heating-ventilating-and-air-conditioning/23-05-00-common-work-results-for-hvac/natural-ventilation
Natural ventilation used to be the most common ventilation method of allowing fresh outdoor air to replace indoor air in a home. Today it's usually not the best ventilation strategy, especially for homes that are properly air sealed for energy efficiency. Natural ventilation also usually doesn't provide adequate moisture control.

When creating an energy-efficient, airtight home through air sealing techniques, it's very important to consider ventilation. Unless properly ventilated, an airtight home can seal in indoor air pollutants. Ventilation also helps control moisture—another important consideration for a healthy, energy-efficient home.

>膨胀配件和回路。商业系统中的大多数管道由金属组成;常见的管道材料包括铜、黑铁、钢和不锈钢。当热作用于金属时,它会发生热膨胀。膨胀的速度取决于金属和所施加的热量。在管道中,有两个方向可以发生热膨胀:周向和纵向。周向延长可以忽略,因此不需要考虑。但纵向膨胀,取决于管道的长度,可以是几英寸或更多。因为管道是刚性的,如果长度的变化没有通过膨胀配件或环提供,管道可能会剪切连接并导致破裂。不同的金属以不同的速度膨胀,但都随着热量的增加而膨胀。 Expansion fittings and loops allow the piping to expand without failure.
