Mengapa penggunaan a gas detektor?
With increasing attention to indoor healthy air quality and energy efficiency, the demand for gas detection instruments and IAQ controllers in the HVAC market has recently become increasingly high. Specifically, the common types of gas detectors/ventilation controllers are CO2 or carbon dioxide detectors. These controllers sense the level of carbon dioxide and once it reaches a sufficiently high level, they will send a signal to control ventilation equipment to remove and replace air in the space. Usually, these sensors will send a proportional signal to the damper motor, which will adjust accordingly to allow fresh air to enter the space. In addition, many controllers also have relays that open or close contacts to turn on or off the power supply for exhaust and/or supplementary fans.
Carbon dioxide, a carbon dioxide detector that can monitor the space occupied by humans or animals to remove over carbon dioxide as a byproduct of respiration. High levels of carbon dioxide are associated with the so-called 'sick building syndrome'. Most building regulations require a certain amount of replenishment or turnover of air to avoid the accumulation of large amounts of CO2 and the resulting health problems. Biasanya, CO2 detektor memiliki dapat disesuaikan set titik, analog sinyal, dan satu atau lebih relai.
Carbon monoxide and nitrous oxide, CO, NO2, detectors are used for operating internal combustion engines in spaces such as parking garages, service garages, small engine workshops, warehouses, underground garages, and generator rooms. Carbon monoxide is a byproduct of gasoline combustion, while nitrogen dioxide is a byproduct of diesel combustion. Mirip dengan CO2 pengontrol, ini unit monitor gas dan kirim proporsional analog sinyal, dan%2untuk membuat relai dalam kontak dengan panggung kipas untuk mengganti beracun udara dalam a diberikan ruang.
Although it is possible to maintain only a constant ventilation rate, this is usually not preferred as the ventilation rate should match the demand and typically change with the demand for these gases. In addition, as mention in the previous article, building ventilation and related building pressure should be balanced. Therefore, in most cases, requirement control systems are desirable. Ini jenis dari sistem akan menghapus beracun udara sebagai dibutuhkan dan mengganti itu dengan an sama jumlah dari segar tambahan udara. The mengemudi faktor dalam sistem adalah benar aplikasi dari IAQ gas detektor/controllers.
