Experimental Research on the Operational Characteristics of Household Air-conditioner with Condenser Heat Recovery

摘要

According to the operational characteristics of household air-conditioning system,the viewpoint of condenser heat recovery and reuse is proposed.A new kind of experimental household air conditioner with condenser heat recovery (HACCHR) system is set up in our laboratory.The HACCHR system can either work in air cooling operational mode or work in circulating water cooling operational mode.Experimental data and comparisons on the operational characteristics between the two modes are given in this paper.Some main performance analytical results of HACCHR system are presented in this paper.The result shows that the inherent performances of the household air-conditioning system is not obviously affected by water cooling and the EERc + w of the HACCHR system is well achieved as long as the condensing temperature is properly controlled.Both the system pattern and our research method have the unique characteristics.Some corresponding empirical relations are obtained from the experimental data and they can be taken as a reference to the development of this new technique.
