Research on the performance of an adsorption heat pump in winter demand response

Abstract

Demand response is an efficient method to flatten the demand curves of end-use customers. This article studies the feasibility of an adsorption heat pump in the demand response of a residential building under winter operating conditions. Stratified storage is introduced into the stratified heat pump system to realize heat recovery, which is also used as a buffer energy source when power shortages occur. This article studies the performance of an adsorption heat pump when the system disconnects the external energy source to simulate the situation of a demand response event occurring through experiments. Moreover, the heating loads of a typical residential building are obtained from the simulations on EnergyPlus. Two day types are selected to evaluate the demand response performance of the system in different situations. The coolest day presents an extreme situation, and the design day represents a normal situation. The demand response potential of the adsorption heat pump is estimated by comparing the heating capacity of the system and heating load curves of the residential building.
