【摘要】：針對冷暖空調(diào)在夏季制冷和冬季制熱運行時,由于室內(nèi)室外工況差異大而造成系統(tǒng)效率低的情況,本文提出了一種新的可變?nèi)萘靠照{(diào)系統(tǒng)。該系統(tǒng)在傳統(tǒng)空調(diào)系統(tǒng)中壓縮機排氣(或者吸氣)的位置接入可變?nèi)莘e的變?nèi)菅b置,通過改變裝置的容積吸入或者吐納制冷劑到循環(huán)系統(tǒng)中,以改善制冷劑在不同工況下的循環(huán)效率。為了對該可變?nèi)萘靠照{(diào)系統(tǒng)進行探究,利用焓差實驗室對搭建的系統(tǒng)進行了實驗研究。實驗在室內(nèi)干濕球溫度為27℃/19℃的情況下,測試了系統(tǒng)在室外干球溫度29℃和35℃的變?nèi)萏匦�。結(jié)果表明,在不同的工況下,改變變?nèi)菅b置的容積,調(diào)整參與系統(tǒng)循環(huán)的制冷劑的質(zhì)量,有利于提高系統(tǒng)在不同工況下的能效。
[Abstract]:In this paper, a new variable capacity air conditioning system is proposed in view of the low system efficiency due to the large difference of indoor and outdoor working conditions during the summer refrigeration and winter heating operation of cold and warm air conditioners. The system connects the compressor exhaust (or suction) position in the traditional air conditioning system to the variable volume varactor, which inhale or inhale refrigerant into the circulatory system by changing the volume of the device. In order to improve the refrigerant cycle efficiency under different conditions. In order to explore the variable capacity air conditioning system, the enthalpy difference laboratory was used to study the system. Under the condition of indoor dry-wet bulb temperature of 27 鈩，
