Abstract

Buluş, bir hava şartlandırma sistemi ile ilgilidir. Hava şartlandırma sistemi, bir çift silindirli değişken kapasiteli kompresör (30) içermekte olup, çift silindirli değişken kapasiteli kompresör (30), üst silindirde bir emme portuna, alt silindirde bir emme portuna ve bir egzoz portuna sahiptir. Hava şartlandırma sistemi ilave olarak bir birinci selenoid valf (71) içermekte olup, birinci selenoid valfin (71) bir ucu, çift silindirli değişken kapasiteli kompresörün (30) egzoz portuna bağlıdır ve birinci selenoid valfin (71) diğer ucu, sırasıyla bir tek yönlü valfe (50) ve çift silindirli değişken kapasiteli kompresörün alt silindirinin emme portuna bağlıdır. Tek yönlü valfin (50) bir ucu, birinci selenoid valfe (71) bağlıdır ve tek yönlü valfin (50) diğer ucu, bir gaz-sıvı ayırıcının iç odacığına bağlıdır. Söz konusu hava şartlandırma sistemi ilave olarak, bir ikinci selenoid valf (72) içermekte olup, ikinci selenoid valf (72), çift silindirli değişken kapasiteli kompresörün alt silindirinin emme portundan gaz-sıvı ayırıcının bir girişine bağlanan boru hattında sağlanır. Bir boşaltma bypass boru hattının bir selenoid valf ile birlikte sağlanması ve ilave olarak alt silindirin emme portu ve gaz-sıvı ayırıcının girişi arasında bulunması sayesinde, alt silindirin emme tarafında bir yüksek basınçlı soğutma sıvısının, gaz-sıvı ayırıcısına doğru basıncı azaltılabilir, bu suretle tek silindirli işleyişten çift silindirli işleyişe geçilirken sistemin stabilitesi optimize edilmiş olur. Bu buluş aynı zamanda bir hava şartlandırma sisteminin kontrol edilmesine yönelik bir yöntem ile ilgilidir.The invention relates to an air conditioning system. The air conditioning system includes a double cylinder variable capacity compressor (30), the double cylinder variable capacity compressor (30) having an intake port in the upper cylinder, an intake port in the lower cylinder, and an exhaust port. The air-conditioning system further includes a first solenoid valve 71, with one end of the first solenoid valve 71 connected to the exhaust port of the double cylinder variable capacity compressor 30, and the other end of the first solenoid valve 71 to a one-way valve, respectively. (50) and is connected to the suction port of the lower cylinder of the double cylinder variable capacity compressor. One end of the one-way valve 50 is connected to the first solenoid valve 71 and the other end of the one-way valve 50 is connected to the inner chamber of a gas-liquid separator. Said air conditioning system further includes a second solenoid valve 72, the second solenoid valve 72 being provided in the pipeline connected from the suction port of the lower cylinder of the double cylinder variable capacity compressor to an inlet of the gas-liquid separator. By providing a discharge bypass pipeline with a solenoid valve and additionally being located between the suction port of the lower cylinder and the inlet of the gas-liquid separator, the pressure of a high-pressure coolant on the suction side of the lower cylinder towards the gas-liquid separator can be reduced, thereby single-cylinder The stability of the system is optimized when switching from operation to double cylinder operation. The present invention also relates to a method of controlling an air conditioning system.
