A vehicular air conditioning unit includes an air-conditioning case and a blower. The blower includes a blower fan accommodated in the air-conditioning case and configured to rotate about a fan axis to cause the air to flow through the case passage, and a blower motor accommodated in the air-conditioning case and configured to rotate the blower fan. The air-conditioning case includes a case body having a case opening hole that is located outward of the blower in a radial direction of the fan axis and opens in the radial direction, and an opening hole cover fixed to the case body to close the case opening hole. The opening hole cover is detachable from the case body. The case opening hole has a size that allows the blower to pass through the case opening hole when the blower is taken out from the air-conditioning case.

Vehicular air conditioning unit

An air conditioning unit for a vehicle includes: an air conditioning case, a blower that draws air from an opening and blows the air radially outward from its rotation axis, a cooler disposed upstream of the blower, and a heater is disposed downstream of the blower. The air conditioning case includes an upper bypass passage through which the air bypasses the heater on an upper side of the heater, a lower bypass passage through which the air bypasses the heater on a lower side of the heater, a first opening provided downstream of the upper bypass passage, and a second opening provided downstream of the lower bypass passage. The opening of the blower faces an air outflow face of the cooler. A passage area of the upper bypass passage is larger than a passage area of the lower bypass passage.
