A measure of the amount of air per unit of time that passes through the device. It is measured either in CFM (cubic foot per minute) or m³/h (cubic meter per hour).
BTU or Btu is the British thermal unit. It is the amount of energy needed to cool or heat 1 pound of water by 1°F. The Btu/h is the unit of power used in HVAC. It corresponds to approximately 0.29 W (Watt).
COP stands for Coefficiant of Performance. It is the ratio between the cooling or heating provided and the electrical power consumption.
A measure of the amount of water per unit of time that the device is able to extract from the ambient air. It is measured in L/h (liter per hour).
EER stands for Energy Efficiency Rating. It measures the ratio of output power to the input power.
HSPF stands for Heating Seasonal Performance Factor. It is the ratio between the seasonal heating output and the electricity used.
A refrigerant is the substance used to « move » the heat outside (or inside) of the room where the device is. We use the refrigerant R-410A as it is environment friendly and allows for the design of smaller and more efficient systems compared to R-22.
SEER stands for Seasonal Energy Efficiency Ratio. It is the ratio between the seasonal cooling output and the electricity used.
Sound Pressure Level :
Sound Pressure is the force of a sound on a surface perpendicular to its direction. It is measured in Pa (Pascal). The lowest sound pressure that can be heard is 2×10-5 Pa. The Sound Pressure Level is a comparison of the measured sound to the lowest sound pressure hearable. The units are expressed in terms of dB (decibel) which is not linear, that is, if the pressure is doubled, the Sound Pressure Level increases by 6 dB. For example, the lowest hearable sound is 0 dB while a quiet room is 40 dB.
