Embedded-type commercial air-conditioner indoor unit

Abstract

The invention provides an embedded-type commercial air-conditioner indoor unit. The embedded-type commercial air-conditioner indoor unit comprises an enclosure body, a draught fan assembly, a heat exchanger and four auxiliary electric heaters. The enclosure body comprises a bottom plate, a square face plate and four side plates. A return air inlet is formed in the center of the square face plate,and four air outlets are formed around the return air inlet in the square face plate. The draught fan assembly is located inside the enclosure body. The heat exchanger is located inside the enclosurebody and on the outer circumferential side of the draught fan assembly. The heat exchanger is provided with a first heat exchange part, a second heat exchange part, a third heat exchange part and a fourth heat exchange part which are bent along the square face plate. The four auxiliary electric heaters are located between the first heat exchange part of the heat exchanger and the draught fan assembly, between the second heat exchange part of the heat exchanger and the draught fan assembly, between the third heat exchange part of the heat exchanger and the draught fan assembly and between the fourth heat exchange part of the heat exchanger and the draught fan assembly correspondingly. The four auxiliary electric heaters are fixedly installed on the bottom plate and the heat exchanger and refer to PTC electric heaters. By means of the embedded-type commercial air-conditioner indoor unit, the influence on the air outlet effect of the air outlets by the auxiliary electric heaters can be reduced; and in addition, the air outlet temperatures of the air outlets can be made more uniform due to the position design of the four auxiliary electric heaters.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, in particular to an embedded commercial air conditioner indoor unit. Background technique [0002] Now when the air conditioner is heating, the heat mainly comes from the heat exchanger of the refrigeration system, and the air exchanges heat with the heat exchanger, thereby increasing the air temperature. The heat in the heat exchanger mainly comes from the high-temperature refrigerant in the air-conditioning system. The high-temperature refrigerant is discharged through the compressor, and then the refrigerant enters the heat exchanger and exchanges heat with the air through the heat exchanger. When users use air conditioners for heating in winter and other low-temperature environments, they hope to quickly increase the indoor temperature. However, in harsh environments such as low-temperature heating, air conditioners generally have poor heating effects and insufficient heating capacit...
