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.

A single-package air conditioner comprising: a housing; an indoor heat exchanger unit housed in the housing; and an outdoor heat exchanger unit housed in the housing, wherein the indoor heat exchanger unit and the outdoor heat exchanger unit together constitute a single cooler/heater unit;the housing is connected to an air conditioner duct suspended from above; andthe cooler/heater unit is removable from inside the housing with the housing kept connected to the air duct.2. A single-package air conditioner as claimed in claim 1, wherein the housing has four side faces thereof formed of four panels, of which three other than one facing a wall are individually removable from the housing. 3. A single-package air conditioner as claimed in claim 1, wherein in the housing is provided a duct that connects to the air conditioning duct and whose height is variable inside the housing. 4. A single-package air conditioner as claimed in claim 1, wherein the cooler/heater is provided with a drain pan for collecting drain water produced in the cooler/heater unit, and the housing is provided with a water collecting sink for collecting and discharging the drain water from the drain pan of the cooler/heater unit. 5. A single-package air conditioner as claimed in claim 1, wherein the housing is connected to the air conditioning duct with or without the cooler/heater unit housed in the housing. 6. A single-package air conditioner as claimed in claim 1, wherein the housing is connected to a drain hose with or without the cooler/heater unit housed in the housing. 7. A single-package air conditioner comprising: a housing; and a removable cooler/heater unit housed in the housing, wherein the cooler/heater unit includes a blower fan casing; anda component forming part of the blower fan casing is removable, such that when the component is removed an opening provides sufficient access to enable removal of a fan provided inside the blower fan casing.8. A single-package air conditioner comprising: a housing; a cooler/heater unit housed in the housing; and heating means, arranged inside the housing, for heating, wherein the heating means is removable through either of left-hand and right-hand side faces of the housing.9. A single-package air conditioner as claimed in claim 8, wherein the heating means is fixed in position with one end thereof engaged with an engagement recess inside the housing and with another end thereof fastened with a screw to a member provided inside the housing. 10. A single-package air conditioner as claimed in claim 8, wherein temperature sensing means for controlling energization of the heating means is arranged above the heating means, the temperature sensing means having a temperature sensing portion thereof housed in a container having a vent through which to allow a flow of hot air in from the heating means. 11. A single-package air conditioner comprising: a housing; and a cooler/heater unit housed in the housing, wherein a hermetic connection portion is formed between a vent opening formed in the housing and the cooler/heater unit.12. A single-package air conditioner comprising: a housing; an indoor heat exchanger, housed in the housing, for exchanging heat with air inside a room; an indoor blower, housed in the housing, for blowing air into the room; an indoor air passage, housed in the housing, through which wind produced by the indoor heat exchanger is passed; an outdoor heat exchanger, housed in the housing, for exchanging heat with air outside the room; an outdoor blower, housed in the housing, for blowing air out of the room; an outdoor air passage, housed in the housing, through which wind produced by the outdoor heat exchanger is passed; and a partitioning member for partitioning at least part of the indoor and outdoor air passages, wherein the partitioning member has a portion thereof formed into a curved-surface portion for guiding the wind passing through one of the indoor and outdoor air passages, andwherein the curved-surface portion is structured as a diffuser portion for diffusing the wind passing through the other of the indoor and outdoor air passages.13. A single-package air conditioner comprising: a housing; an indoor heat exchanger, housed in the housing, for exchanging heat with air inside a room; an indoor blower, housed in the housing, for blowing air into the room; an indoor air passage, housed in the housing, through which wind produced by the indoor heat exchanger is passed; an outdoor heat exchanger, housed in the housing, for exchanging heat with air outside the room; an outdoor blower, housed in the housing, for blowing air out of the room; an outdoor air passage, housed in the housing, through which wind produced by the outdoor heat exchanger is passed; and a partitioning member for partitioning at least part of the indoor and outdoor air passages, wherein the partitioning member has a portion thereof formed into a curved-surface portion for guiding the wind passing through one of the indoor and outdoor air passages, andwherein the curved-surface portion faces an outdoor inflow opening, and has an arc-shaped section whose radius R satisfiesmin( Ra,Rb)≧R,where Ra represents a dimension of a portion of the outdoor inflow opening facing the partitioning member and Rb represents a dimension of the outdoor air passage.14. A single-package air conditioner as claimed claim 13, wherein the following conditions are additionally satisfied: Rb≧Ra and R≈Ra.
