Full fresh air conditioning of forced air cooling

The utility model discloses a full fresh air conditioning of forced air cooling through setting up a conventional full fresh air conditioning of forced air cooling, increases one steam by -pass line and the other solenoid valve of steam in one of them compressor side, increases the control to the other solenoid valve of steam at conventional full fresh air conditioning of forced air cooling on the basis of, and through the by -pass line design, when making steam bypass valve standard -sized sheet, whole brand -new wind forced air cooling cooler air -conditioner volume infinitely variable control through the make -break time proportion of controlling the other solenoid valve of the compressor steam, is realized to 10% when the closing that the actual cold volume output of the compressor is about the steam bypass valve, reaches to exceed wind -warm syndrome degree precision design target, new trend forced air cooling cooler air -conditioner measures infinitely variable control, reaches to exceed wind -warm syndrome degree precision design target, because whole full fresh air conditioning of forced air cooling is the configuration of ordinary scroll compressor, only increases item exhaust pipe and one exhaust solenoid valve, so the cost of whole unit is lower, accords with the principle of economy.
