Study on the effects of air conditioners under intermittent operation conditions on residential demand response

Abstract

This paper studies the applicability of the intermittent operation of air-conditioners in residential building demand response (DR). Firstly, the thermal inertial model of the building is established based on the dynamic heat transfer theory and verified by the experimental platform; then, based on the validated thermal inertial model of the building, the power demand change of intermittent operation of a residential air conditioner is simulated; because intermittent operation of an air-conditioner cannot achieve a smooth reduction of power demand, this article studies a group of residential building further and evaluates the DR effect of multiple air-conditioners interacting with each other. The study found that by use of the thermal inertia of the building, intermittent operation of air conditioners can maintain the indoor temperature within a certain range while achieving temporary reduction in electricity demand; through the cooperation between multiple air conditioners, the long-term stable reduction can be achieved under the premise of guaranteeing the temperature of the air-conditioned rooms.
