Supply unit
The advantage supply unit for an apartment is its complete set. You get a full-fledged system in one case, it remains to lay the air duct system, supply power and install the device itself.
The main indicators for the selection of equipment are the volume of supply air and the resistance of the air duct system. These parameters are acquired by engineering calculation at the design stage. Next, the selection of the model and manufacturer of equipment is carried out.
The Alter Air company has been implementing various ventilation systems and works only with trusted manufacturers for 13 years. Therefore, we recommend the following brands of supply equipment:
- Systemair;
- Salda;
- Ostberg.
The presence of air supply obliges to organize a high-quality extraction of the exhaust air to organize the correct air exchange. Thus, it is recommended to adhere to the principle – “The amount of air supplied is equal to the amount of exhaust air”. That is, if we supply 100 cubic meters of air, then we exhaust 100 cubic meters. Therefore, do not forget about household exhaust fans.
The disadvantage of the supply unit is that a large amount of electricity is spent on heating the air, and then the warm exhaust air is thrown out into the street.
In the case when the street temperature is 0 °C, and the air temperature in the room should be +22 °C according to Construction Norms & Regulations, 1 kW of electricity will be required. If the outside air temperature is -22 °C, then 3 kW of electricity will be needed. However, the amount of energy consumed depends on the volume of supplied air.
For a more illustrative example, let's calculate the amount of kW of electricity for 400 m3 of supply air using the formula:
Q= G×R0×C×(-to+tin), where
Q - the amount of electricity;
G - volume of heated air;
ρ - air density;
C - specific heat capacity of air;
to - outdoor air temperature;
tin - indoor air temperature;
G = 400m3; ρ = 1.2 kg/m3; C = 0.24 kcal ⁄ (kg x °C); to = -22 °C; tin = +22 °C.
In this way,
Q = 400 × 1.2 × 0.24 × (22 + 22) = 5068.8 kcal = 5.9 kW
As a conclusion, the air supply unit will be costly to operate. In addition, do not forget that the heated air will be thrown out into the street through exhaust fans in the “dirty areas” (a bathroom, a toilet, a dressing room, etc.). An air supply unit today is an impractical solution, since it consumes a large amount of energy during operation.
Most consumers prefer air-handling units with heat recuperation. The device allows you to utilize the heat (exhaust warm air), which is taken by the exhaust fan in the bathroom, and use thermal energy to heat the supply air, using a plate recuperator. Thus, you will significantly reduce the cost of electricity.
