Anti-electromagnetic interference marine air conditioner outdoor unit

Abstract

The invention relates to an anti-electromagnetic interference marine air conditioner outdoor unit. The air conditioner unit comprises a stainless steel shell, a digital scroll compressor, a liquid storage pipe, an L-shaped condenser, an axial flow fan and a drying filter, wherein the digital scroll compressor, the liquid storage pipe, the L-shaped condenser, the axial flow fan and the drying filter are installed in the stainless steel shell, the digital scroll compressor is connected with the L-shaped condenser, the L-shaped condenser is fixed with two adjacent side surfaces of the stainless steel shell, an outlet of the L-shaped condenser is connected with the liquid storage device, the liquid storage device is connected with the drying filter, the axial flow fan is fixed on the stainlesssteel shell, and an air outlet of the axial flow fan faces the L-shaped condenser. Due to the fact that the L-shaped condenser is adopted, especially the digital scroll compressor is adopted, the outdoor unit is small in size, stepless in capacity output, high in energy efficiency ratio, stable in indoor temperature control, high in dehumidification capacity, good in oil return performance, freeof electromagnetic interference, high in reliability and good in tightness, and particularly achieves the energy-saving effect.

Description

technical field [0001] The invention relates to a high-performance outdoor unit of a marine split air conditioner, which belongs to the technical field of air conditioners. Background technique [0002] At present, the variable refrigerant flow air-conditioning system has been widely used in practical engineering, and major air-conditioning manufacturers have launched corresponding products. In the 1990s, my country introduced frequency conversion technology from Japan. And so on have also developed the frequency conversion air conditioning system. [0003] Frequency conversion: The capacity of the compressor is changed by the speed of the frequency conversion compressor motor. When the indoor load requirement increases, the frequency of the compressor motor increases, resulting in faster motor speed and higher capacity. Likewise, as the indoor load demand decreases, the frequency of the compressor decreases, thereby reducing capacity. [0004] From the variable frequency c...

AI Technical Summary

Problems solved by technology

The inverter control board generates a lot of heat, which is easy to burn out in summer

[0009] Frequency conversion controllers will generate high-order harmonics, causing problems such as overheating of transformers / capacitors, reduced accuracy of precision instruments, and interference with the transmission of TV signals, mobile signals, and subway station signals, etc.

In order to solve the problem of electromagnetic interference, noise filters or choke coils need to be added to the outdoor unit / indoor unit, which increases the cost of the system

[0010] The existing marine split air conditioner high-performance outdoor unit system uses two single-sided condensers combined, the outdoor unit is large in size and heavy in weight; most of the existing marine split outdoor units use ordinary hermetic compressors, and the ones with better performance use frequency conversion compression However, inverter compressors also have shortcomings such as intermittent capacity output, low energy efficiency, unstable indoor temperature control, low dehumidification performance, difficult oil return, and large electromagnetic interference.
