In the course of the hotter months, air-source heat pumps operate equally to central air conditioners by using a refrigerant to extract heat from indoors and expelling it outdoors throughout the compressor. When running through the cold-weather conditions months, heat pumps make use of a reversing valve to modify from cooling to heating modes to operate in reverse.
BDD stands for Backdraft Damper. BDD is employed to make certain air flows in a single direction. It prohibit air from flowing within the reverse route by utilizing a mechanism to instantly near the damper in the event the air is flowing in the wrong direction.

Pure CSS is created by Yahoo and is also utilized for making more rapidly, attractive, and responsive Internet websites. It can be employed as an alternative to Bootstrap. On this page, we w
ECM stands for Electronically Commutated Motor. ECM is often called DC brushless motor. It's really a high-effective motor that typically found in FCU, ceiling ducted device as well as other modest-capability air conditioners. ECM incorporates a motor efficiency course ranking of no less than IE3 and earlier mentioned.
ATC stands for Automated Temperature Command. ATC is made use of to point the temperature and humidity in sure sections/zones of a constructing is quickly controlled because of the air con system.
NRD stands for Non Return Damper. NRD is usually a kind of damper that permits air to maneuver in a single course only. It use the drive of gravity and material pounds to close.
