The invention provides a multi-compressor efficient type unit which can improve an oil separation rate, solve the problems that in the prior art, oil imbalance and shortage exist among parallel compressors, effectively improve an integrated part load value (IPLV) of a performance parameter value in partial loading of the unit, improve comprehensive energy efficiency of the unit and enable the unit to operate safely, efficiently and stably for a long time. The multi-compressor efficient type unit comprises a flooded evaporator, a condenser, an oil separator, a plurality of compressors and a control device. Each air exhaust opening of each compressor is connected with an air inlet of the oil separator. An oil outlet of the oil separator is connected with an oil inlet of each compressor through an oil returning device. An air outlet of the oil separator is connected with an inlet of the condenser. An outlet of the flooded evaporator is connected with each air absorption opening of each compressor and an inlet of the flooded evaporator is connected with an outlet of the condenser through a swelling throttling gear. An outlet of each compressor is respectively connected with an inlet of each compressor through an injection oil returning device. The injection oil returning device is connected with an oil returning pipe of the flooded evaporator.
Description
technical field [0001] The invention relates to the technical field of air conditioning units, in particular to a multi-compressor high-efficiency unit. Background technique [0002] "Energy saving" and "environmental protection" have become the development theme of today's refrigeration and air conditioning industry, and energy-saving products are the trend of social development. Therefore, domestic air-conditioning companies are actively developing high-efficiency units to meet market demand, the most important of which is the introduction of high-energy-efficiency energy-saving products such as flooded units. Compared with the dry unit, the flooded unit has a small heat transfer temperature difference, a small outlet superheat, and an increased evaporation temperature. The heat exchange area is effectively used, and the heat exchange capacity and efficiency are also greatly improved, which is more efficient and energy-saving. [0003] However, the current multi-compresso...
