ITPEC FE Morning April 2021 Question 73
ITPEC FE Morning April 2021 — Question 73 of 80
HEMS stands for Home Energy Management System. It connects multiple home appliances through a network to visualize energy usage and optimize power consumption in a household.
Why not others:
- (b) Describes a power conditioner that converts electricity from solar panels and fuel cells for household use — not HEMS.
- (c) Describes a home appliance recycling system that reuses parts to reduce waste — not HEMS.
- (d) Describes a heat pump water heater (e.g., EcoCute) that generates heat efficiently — not HEMS.
Key rule: HEMS = network of home devices + energy visualization + consumption optimization.
