Technical FAQs 4

What is solar PV driven air conditioner?

The design of direct solar PV driven air conditioner based on stand-alone solar PV system is studied. The air conditioner is driven directly by solar PV module through an inverter. No grid power is connected. In order to balance the solar PV power and load power and reduce the cost, a small buffer battery is installed.

What is solar air conditioning system?

Solar air conditioning system developed in the present study is based on the concept of direct solar driven. Battery acts only as buffer energy storage for balance of solar and load power, and smooth operation of compressor under variable solar radiation.

How do solar air conditioners work?

An inverter is used to convert PV power into ac power to drive the air conditioner. The battery can supply power for less than 1 h during low solar radiation periods. Hence, the cooling system may suffer from loss of power. In the present study, six solar air conditioners are designed and tested.

Can solar air conditioner design be applied to electric vehicles?

If the present solar air conditioner design is applied to electric vehicles, energy consumption, weight, space, and cost of solar PV system need to be considered. The design to reach high OPB and RF will be the major concern in electric vehicle. Hence, the design with rpL = 2 for OPB = 0.8 at solar irradiation IT = 400 Wm −2 may be proper.
