The air conditioning water heater system can operate in five modes: waterheating only, spacecooling and waterheating, spaceheating and waterheating, spacecooling, spaceheating. Comparatively, the system can provide much better energy performance and higher equipment utilization throughout a year, and cause less thermal pollution than heat pump water heater and mon air conditioner. A prototype with five modes was assembled and tested at the ambient temperature from 7℃ to 43℃, especiallywhen frosting. When it works in the waterheating mode, it can supply 55℃ hot water within two minutes, and thecondensing pressure is just same with mon air conditioner. When some modes switch, the temperature of theoutlet hot water is constant. Theoretical analysis and experimental study were done to the ACWH in this thesis:1. The prototype was tested in the airconditioner laboratory of GREE. The testing data indicate that the prototypeaccords well with the national standards of air conditioner and heat pump water heater.2. Based on the experimental results, analysis was done on the ACWH in main operating modes and some importantconclusions were given,The results indicate that the new system can save energy through multiduties, and it can work stably in five workmodes with high efficiency. Compared with other models, the new system also includes airconditioning unit andwater heater unit, but with fewer ponents and higher reliability. Based on mon air conditioner, this systemcan offer a practicable solution coupling air conditioner and water heater. It must be changing the markets of bothair conditioner and water heater. 1. INTRODUCTIONThe heat pump water heater (HPWH) has been used since 1950s, mainly for household applications. It absorbs heatenergy from the ambient air to acquire hot water. In the last 20 years, the study intends to design heat pump waterheater with high reliability and practicability, and many manufacturers turn to offer this production based onenvironmental protection and energy saving. In South Africa, HPWH has penetrated 16 percent of the market sharefor mercial water of the highly primary cost, it is difficult to bee the alternative to the mon water heater. However, ifwe can offer an air conditioner coupled with HPWH system, which can act as air conditioner and water heater withthe main ponents such as heat exchangers, pressor, fourway valve, and capillary tube, the primary cost willbe reduced and it can realize multifunction easily. In summer, with the recovery of the waste heat of condensation, itcan offer “free” hot water, and also can improve the coefficient of performance (COP) of the air conditioner. Whenair conditioner is not required in spring and autumn, it can operate in HPWH mode. As the enhancement of the yearroundutilization, it can be more efficient and is expected to bee a strategy solving the air conditioning and hotwater applications. Here we demonstrate an air conditioning water heater (ACWH) system, and the performanceanalysis is described in this article.1. THE PRINCIPLE OF ACWHThe schematic diagram of air conditioning water heater system is shown in Figure 1. The system can offer thefollowing five operating modes. Mode 1 is only for heating water。 mode 2 can act as spacecooling and waterheating。mode 3 can realize both spaceheating and waterheating。 the other two modes are the same with themon airconditioning circles. The switching among all these modes is by means of onoff controls of thesolenoid valves and fourway valve. Each mode will be demonstrated as follows. Water Heating Mode Water Heating ModeThe system can operate in two heating modes. The one is direct heating water。 the other is heating water with waterrecycle in the adiabatic water tank. The controller can adjust the operating mode according to the water level sensorsin the tank. A water valve is placed at the hot water outlet which can be adjusted to control the water flow and keepthe condensing pressure constant. When the tap water goes into the waterrefrigerant heat exchanger (WRHE), itwill be heated to 5055 directly within two minutes. If needed, ℃ the outlet water temperature can be set byadjusting the water shown in Figure 1, when the power is on, the pressor sucks lowpressure refrigerant gas and then dischargeshighpressure gas into waterrefrigerant heat exchanger (WRHE), where refrigerant is condensed and water is heateddirectly. After heat exchanges, the liquid refrigerant flows across fourway valve, then it is throttled to lowtemperatureand lowpressure liquid and gas by an electronic expansion valve. Refrigerant flows into outdoor aircooledcondenser where it is evaporated and bees lowpressure gas. When the lowpressure gas returns to thepressor, the circle begins again. In this mode, valve 1 is closed and valve 2 is open. When heating water, theoutdoor aircooled unit acts as evaporator, and the indoor fan doesn’t run. The COPw is presented as a function ofpower Qw and the electric power W as shown in Equation (1).COPw=Qw / W=MC△T (1)Where M is
