Indoor unit of fresh air conditioner

Abstract

The invention provides an indoor unit of a fresh air conditioner. A fresh air device is additionally arranged on the traditional air conditioner indoor unit, so outdoor air can be introduced into a room through the fresh air device even if a window is closed during the cooling or heating process of the air conditioner, continuous and fresh air can be provided for a closed indoor space, the oxygencontent of the indoor air can be increased, and air conditioning diseases can be eliminated. The ratio of the distance between the air outlet of the fresh air device and the air inlet of the indoor unit to the length of the air outlet along the transverse direction of the shell is set between 2: 1 and 1: 1. In this way, the air flow sent out from the air outlet is more easily sucked into the air inlet again, so that more air sent out from the air outlet enters the air inlet and exchanges heat with a heat exchanger. The outdoor fresh air sent into the room reaches the indoor set temperature quickly after heat exchange by the indoor unit heat exchanger, so that the indoor temperature does not fluctuate greatly, the indoor temperature keeps stable, and a comfortable and healthy environment isprovided for users.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a fresh air air conditioner indoor unit. Background technique [0002] An air conditioner is a widely used household appliance. It generally has heating and cooling functions.

However, the cost is too high. Generally, the price of fresh air devices suitable for households is 4,000, 5,000, or even tens of thousands, which is more expensive than air conditioners and subverts the general Chinese people's concept of cost-effective consumption. Therefore, how to improve the structure of fresh air devices and reduce Price is a big trend right now
