An air conditioner with thermal storage is developed in the present study to replace battery storage, called “HyPV-Z”, which utilizes excess PV power to converted into thermal energy to store in hot or cold water tank. Three kinds of systems are developed: 1. HyPV-Z1: using a FCU (fan-coil unit) installed in cooling room to utilize the stored cold water for cooling of room. 2. HyPV-Z2: improvement I of PV-Z1 to move the FCU to outdoor to cool the condenser to reduce power consumption of air conditioner. 3. HyPV-Z2a: improvement II of PV-Z1 to eliminate the outdoor FCU and direct cool the heat exchanger after the condenser to reduce condenser temperature. The following conclusions are made by the research: 1. Three systems developed are proved experimentally to be able to use thermal storage to replace battery to reduce the HyPV-A cost. 2. HyPV-Z1 utilize excess PV power for cold storage and released when air conditioning is turned on. The COP reaches 6.01 which is higher than the original air conditioner before modification with COP 5.2. This proves the cold storage is effective in replacing battery storage. 3. HyPV-Z2 obtainCOP 6.04 running in heating mode with heat release from the hot storage. This is about 30% higher than the COP of the original air conditioning running in heat mode. This proves the hot storage is effective in replacing battery storage. 4. HyPV-Z2a obtain a COP 4.33 when running with cooling mode with cold release fro the cold storage, about 42% higher than that of the original air conditioner running in cooling mode. This proves the cold storage is effective in replacing battery storage. Bin-Juine Huang 黃秉鈞 2017 學位論文 ; thesis 75 zh-TW
