摘要:
Disclosed are viologen derivatives as an electrochromic material having improved stability and lifetime, a metal oxide electrode including the same, and an electrochromic device using the viologen derivative as an electrochromic material. The viologen derivative includes a suitable regulator group capable of increasing ΔE that is a potential difference between E1 (potential at the first redox reaction) and E2 (potential at the second redox reaction). When ΔE increases, the mole fraction of viologen molecules present in the second reduction state decreases. Therefore, it is possible to lower the mole fraction of viologen molecules present in an irreversibly reduced state at an applied potential, thereby increasing the lifetime of an electrochromic material and an electrochromic device.

摘要:
An automatic defogging system of a vehicle according to an exemplary embodiment of the present invention includes: an input unit used for receiving a directly sensed window relative humidity value from a defogging sensor so as to directly sense a humidity generation degree in a window; a controller which controls operations of an air conditioning system programmed as a type of a logic that is selectively and phasedly controllable depending on the sensed relative humidity and; an output unit that is a selection mode of the air conditioning system that can be controlled by the controller. Accordingly, an automatic defogging system of a vehicle and a control method thereof automatically removes fog or frost on an inner surface of a window while maintaining comfortable conditions inside a vehicle.
摘要:
Disclosed herein is a flash tank of a two-stage compression heat pump system that can perform cooling and heating with a separate type intercooler and a high-stage compressor protecting device. The system comprises a fluid-level detecting sensor for detecting the fluid-level of the refrigerant, an alarm sensor for notifying the saturated state of the refrigerant filled in the flash tank, an evaporator pressure sensor for measuring and notifying the pressure of the refrigerant flowing into the evaporator, a condenser pressure sensor for measuring and notifying the pressure of the refrigerant flowing out of the condenser, a flash tank fluid-level controller for receiving signals from the above sensors and controlling intermediate pressure and the fluid-level of the flash tank, and a bypass valve controller for controlling a bypass valve that receives signals from the alarm sensor and allowing a refrigerant to directly flow from the low-stage compressor to the high-stage compressor.
