Single-package air conditioner

摘要

A single-unit air conditioner has a housing and a cooler/heater unit housed in it. The cooler/heater unit can be put into and taken out of the housing with the housing kept connected to an air conditioning duct. Of the four panels forming the four side faces of the housing, three other than the one facing a wall can be removed individually from the housing. The cooler/heater unit has an indoor heat exchanger unit including an indoor blower, which is housed in a fan casing having an outflow opening that can be widened by removing a member so that the outflow opening can be used as an opening through which to maintain a fan. The indoor heat exchanger unit includes heating means for heating, which can be fitted and removed through either of the left-hand and right-hand side faces of the housing. Inside the housing are provided an indoor air passage and an outdoor air passage, of which at least part is partitioned by a partitioning member. The partitioning member has a portion thereof formed into a curved-surface portion, which guides the wind passing through one of the indoor and outdoor air passages.
