Problems solved by technology

[0002] The disadvantages of commercially available window-type and split-type air conditioners are: the mechanical vibration and electromagnetic noise of the window-type air conditioner are relatively large, and the quietness is poor; although the split-type air conditioner partially reduces indoor noise (as well as cross-flow fan blades and motor noise) , but the two indoor and outdoor units are connected by long refrigeration pipes, and there are four ports, resulting in easy leakage of refrigerant or blockage of pipes, and it is not convenient to replace the indoor air. The structure of the whole machine is complicated, and it is troublesome to install and move the machine

Embodiment Construction

[0011] refer to figure 1 The outdoor unit 1 includes all components of the refrigeration system (compressor, indoor and outdoor air heat exchanger, axial flow fan and centrifugal fan, etc.), and its structure is similar to that of the existing window air conditioner; 1. The air outlets are respectively connected with the wall-piercing pipes 7 and 12, and the wall-piercing pipes enter the room and are connected with the indoor unit 9. The wall-through pipes 7A and 12B use hard plastics, and the cross-section can be made into a circle. The outdoor unit 1 is placed on a metal tripod, and the wall-through pipes A and B can pass through the window (the structure of the window does not need to be destroyed, as long as one or two pieces are removed) glass) or wall holes into the interior.

Abstract

The invention relates to new type air internal circulation type room air conditioning unit. Its indoor control box only includes micro machine remote wind system and filtering net. Its outdoor unit includes electric and air internal circulation system, and whole refrigeration system. And the outdoor is connected with the indoor. Indoor air heat exchanger is made up of preheat exchanger and secondary heat exchanger, and removed wet compression for compressor.

Description

technical field [0001] The invention relates to an air internal circulation room air conditioner, in particular to a quiet and high-efficiency air conditioning unit. Background technique [0002] The disadvantages of commercially available window-type and split-type air conditioners are: the mechanical vibration and electromagnetic noise of the window-type air conditioner are relatively large, and the quietness is poor; although the split-type air conditioner partially reduces indoor noise (as well as cross-flow fan blades and motor noise) , but the indoor and outdoor units are connected by long refrigeration pipes, and there are four ports, which leads to easy leakage of refrigerant or blockage of pipes, and it is not convenient to replace the indoor air. The structure of the whole machine is complicated, and it is troublesome to install and move the machine. Contents of the invention [0003] The object of the present invention is to provide a kind of air internal circul...
