Figure BDA00002785351700061
Therefrom as can be known, as sink temperature T 2During decline, thermal efficiency η raises, and reduces to the heat of low-temperature receiver discharging, if sink temperature T2 declines by a big margin, namely sink temperature is very low, and thermal efficiency η is very high, and is very little to the heat of low-temperature receiver discharging.Infer thus, the cryogenic substance that usable temp is quite low declines to a great extent sink temperature T2, thereby significantly reduces to the heat of low-temperature receiver discharging, effectively improves engine efficiency.
The cryogenic substance that temperature is lower (such as liquid oxygen, liquid nitrogen or liquid helium etc.), need to consume more energy in manufacture process, but with regard to unit mass, the contribution that engine thermal efficiency η is promoted is larger, like storing the energy in the very low material of temperature, the concept that is equivalent to a kind of novel battery, described cryogenic substance can wait the very low energy of cost to make with the rubbish electricity, thereby effectively reduces the user cost of motor.
