An air-sending device includes a propeller fan, a bell mouth surrounding an outer periphery of the propeller fan, a fan grille disposed downstream of the bell mouth and including a plurality of first crosspieces. An edge of the air outlet of the bell mouth includes a varying portion whose distance from a rotation axis of the propeller fan varies. In a cross-section of any of the plurality of first crosspieces that is perpendicular to a longitudinal direction of the any of the plurality of first crosspieces, a virtual line segment connecting an upstream side end portion and a downstream side end portion is defined as a first virtual line segment. At the portions of the plurality of first crosspieces disposed on the inner circumference side of the varying portion, the angle between a virtual line segment parallel to the rotation axis and the first virtual line segment is changed. 1. An air-sending device comprising:a propeller fan configured to rotate about a rotation axis;a bell mouth having an air outlet and surrounding an outer periphery of the propeller fan; anda fan grille disposed downstream of the air outlet in a direction of airflow generated by the propeller fan, the fan grille including a plurality of first crosspieces;each of the plurality of first crosspieces having an upstream side end portion and a downstream side end portion, the upstream side end portion being positioned on an upstream side of the airflow, the downstream side end portion being positioned on a downstream side of the airflow,wherein the air-sending device is configured such thatwherein a cross-section of any of the plurality of first crosspieces, the cross-section being perpendicular to a longitudinal direction of the any of the plurality of first crosspieces,a virtual line segment connecting the upstream side end portion and the downstream side end portion is a first virtual line segment,an acute angle of angles formed by the first virtual line segment and a virtual line segment ...

A pipe unit is provided for a refrigerant circuit which performs a vapor compression refrigeration cycle by circulating a refrigerant. The pipe unit includes a pipe body having a liquid pipe through which a liquid refrigerant for the refrigerant circuit flows and a gas pipe through which a gaseous refrigerant for the refrigerant circuit flows; and a heat insulator covering each of the liquid pipe and the gas pipe separately. The liquid pipe and the gas pipe, each of which is covered with the heat insulator, are fixed together to form a single piece. Such partial unitization of the refrigerant circuit allows for reduction in the number of days required for installation of an air conditioner. 1. A method for fabricating a pipe unit for an air conditioner , the pipe unit being provided for a refrigerant circuit which performs a vapor compression refrigeration cycle by circulating a refrigerant , the method comprising:a step of fabricating a liquid pipe through which a liquid refrigerant for the refrigerant circuit flows and a gas pipe through which a gaseous refrigerant for the refrigerant circuit flows;a step of covering each of the liquid pipe and the gas pipe with a heat insulator; anda step of fixing together the liquid pipe and the gas pipe, each of which is covered with the heat insulator, to finish the fabrication of the pipe unit.2. A method for installing an air conditioning device including an indoor unit , an outdoor unit connected to the indoor unit through a refrigerant pipe and a refrigerant circuit in which a refrigerant is circulated between the indoor and outdoor units and , the method comprising:a part fabrication step of fabricating a pipe unit provided for the refrigerant circuit; andan installation step of installing and connecting together the outdoor, indoor and pipe units in a building, wherein a step of fabricating a liquid pipe through which a liquid refrigerant for the refrigerant circuit flows and a gas pipe through which a gaseous ...
