| description | PURPOSE: A reverse rotation prevention apparatus of a compressor for a freezing unit and a heat pump and a control method thereof are provided to prevent the damage of a compressor due to a reverse rotation and to extend the lifespan of a heat pump and a freezing unit to which a scroll compressor is applied. CONSTITUTION: A reverse rotation prevention apparatus of a compressor for a freezing unit and a heat pump comprise a pipe for detecting intake pressure(22), a pipe for detecting discharge pressure(32), a differential pressure switch(40), and an interruption contact. One end of the pipe for detecting intake pressure is connected to the given position of the refrigerant gas intake pipe(20) of a scroll compressor(100). One end of the pipe for detecting discharge pressure is connected to the given position of the refrigerant gas discharge pipe(30) of the scroll compressor. The differential pressure switch is installed on the other end of the pipe for detecting intake pressure to operate depending on the predetermined differential pressure between the discharge pressure and the intake pressure of refrigerant gas. The interruption contact is connected with the differential pressure switch by a wire and stops the compressor. |
