Problems solved by technology

[0002] The air conditioner only heats through the compressor refrigeration system, which generally has the problem of low heating efficiency and the heating effect that the user expects.
In order to overcome the above problems in the prior art, the surface of the indoor heat exchanger is covered with an electric heater to assist in heating the ambient air entering the casing, but this method not only takes up more space inside the casing, but makes the indoor heat exchanger The distance between the heater or electric heater and the fan is too close to increase the wind resistance, and the heat generated by the electric heater cannot directly enter the fan, resulting in waste of heat

Abstract

The invention provides a cabinet type air conditioner indoor unit which comprises a case provided with a case air inlet and at least one case air outlet, at least one air feeding assembly arranged inthe case and provided with a centrifugal fan, an indoor heat exchanger arranged on an air inlet path between the case air inlet and the air feeding assembly, and at least one group of electric heatingpipes. The indoor heat exchanger comprises refrigerant heat exchange pipes and a fin group extending along the vertical direction and provided with multiple pipe inserting holes; and the refrigerantheat exchange pipes penetrate through part of pipe inserting holes so as to be fixedly connected with the fin group. The at least one group of electric heating pipes penetrate through the other part of pipe inserting holes so as to be fixedly connected with the fin group. According to the cabinet type air conditioner indoor unit provided by the invention, the original pipe inserting holes of the indoor heat exchanger are used for installing the electric heating pipes, so that no extra space is occupied, the air inlet area is larger, the air resistance is small, and the air feeding amount of the air feeding assembly is further improved.

Description

technical field [0001] The invention relates to the field of air treatment, in particular to a cabinet type air conditioner indoor unit. Background technique [0002] The air conditioner only heats through the compressor refrigeration system, which generally has the problem of low heating efficiency and the heating effect expected by users. In order to overcome the above-mentioned problems in the prior art, the surface of the indoor heat exchanger is covered with an electric heater to auxiliary heat the ambient air entering the casing, but this method will not only occupy more space inside the casing, but also make the indoor The distance between the heater or electric heater and the fan is too close to increase the wind resistance, and the heat generated by the electric heater cannot directly enter the fan, resulting in waste of heat. Considering comprehensively, it is necessary to design a cabinet-type air conditioner indoor unit with high heating efficiency that does not...
