The variable load regulation technology in testing of energy efficiency evaluation of gas water heater is studied. The control scheme of using electric control valve as the primary method and frequency control motor as the auxiliary method is determined. According to cascade control algorithm, the con...
In such applications, gas sensors have become a main source of power consumption because energy conversion efficiency of the microheater is relative over a wide range of operating temperatures. To improve the energy-conversion efficiency of gas-sensor microheaters, this paper proposes integrated switch...

A CO2 heat pump water heater (HPWH) can provide hot water with a relatively high COP and consume significantly less energy than all electric or gas water heaters. This study reviews and analyses the existing CO2 HPWHs both in industrial and residential sectors, where the low-temperature and ...
It can be seen that the energy storage system becomes very large in the given approach that assumes neither efficiency improvements nor energy imports. That distinguishes this work to the studies mentioned in the introduction. Regarding the transportation sector, energy demand in Scenario 1 is by fa...
