Commercial air conditioner

Abstract

The invention discloses a commercial air conditioner. The air conditioner comprises two sets of refrigerating systems, wherein each refrigerating system comprises a compressor component, a pipeline component, a condenser component and a cut-off valve component; the compressor component is partitioned into an upper part and a lower part through a compressor mounting plate; a lower compressor is arranged on a chassis; and an upper compressor is arranged on the compressor mounting plate. The commercial air conditioner has the advantages of reducing overall size of the compressors on the premise of ensuring the quality and reliability of an air conditioning unit, enhancing the refrigerating and heating capacities and energy efficiency ratio of the air conditioner, reducing noise, lowering the material cost and transportation cost of a product and improving the market competitiveness of the product.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a commercial air conditioner. Background technique [0002] The air conditioner is the air conditioner (air conditioner), and the hanging air conditioner is a unit used to provide processing air to the space area, which is generally closed. Its function is to adjust the temperature, humidity, cleanliness and air velocity of the air in the room or closed space and the area to meet the requirements of human comfort or process. Its working principle is: the compressor compresses the gaseous refrigerant into a high-temperature and high-pressure liquid refrigerant, and then sends it to the condenser outdoor unit to dissipate heat and becomes a normal temperature and high-pressure liquid refrigerant, so the outdoor unit blows out hot air; Sometimes there is a part called a four-way valve, which makes the flow direction of the refrigerant in the condenser and evaporator opposite to that...

AI Technical Summary

Problems solved by technology

[0003] At present, the existing commercial air conditioners on the market use the upward air outlet method, and their volume is relatively large, especially thick in the thickness direction, and the noise is relatively high. At the same time, due to the difference in wind speed between the upper and lower windward sides of the heat exchanger Larger, the lower part of the heat exchanger has poor heat transfer effect and low efficiency due to the low air flow rate, and it is easy to cause the bias flow phenomenon of the heat exchanger, so that the overall efficiency and utilization rate of the heat exchanger are not high, resulting in the failure of the whole machine The energy efficiency and capacity are relatively poor, and the cost of the sheet metal parts of the box and the fan is very high. The material cost, packaging cost and transportation cost of the whole machine will be much higher, and the market competitiveness is lacking.
