LPF stands for Low Pass Filter. LPF is used to block unwanted substantial frequency indicators by allowing only selected small frequency signals to pass through. It is largely a filter for electrical alerts. LPF increases the electronics and Management systems of assorted air-con models.
CRU means Condensate Restoration Device. CRU is really a tank or simply a system that recovers the condensate water produced by the air conditioners in the developing. It is actually an energy conservation system that reuse the condensate water for other needs for instance plant watering and drainage cleaning.
Air Conditioner – Linked to The within cooling coil, the compressor pumps refrigerant back and forth, extracting heat and humidity with the indoors.
CWR means Condenser Drinking water Return. CWR is usually located in the chilled water system format and schematic drawings. Additionally it is popular to have the CWR phrase bodily painted to the condenser h2o pipe to point the condenser drinking water circulation course within the chiller towards the cooling tower.
Competently improving upon air high quality and ventilation in indoor environments mostly will involve working with Superior filtration systems along with the management of humidity as a result of humidifiers and dehumidifiers.
PIU means Energy Induction Unit. PIU can be a secondary air-con device that is frequently Positioned close to the focus on cooling/heating Place. It's going to take in air conditioned by the primary air-con device for example an AHU, and even further interesting/warmth the air to your concentrate on Area temperature.
EER means Vitality Effectiveness Ratio. EER is yet another universal measurement for your Vitality effectiveness of air conditioners. EER is calculated by dividing the ability in BTU by the ability enter in W.
PAHU stands for Pre-Cooled Air Managing Device. PHAU is usually a form of air managing unit that processed the out of doors air.
