Claims

[Scope of utility model registration request]

(1) In an automobile air conditioner in which an evaporator is housed in a cooler unit case, a refrigerant inflow pipe and a refrigerant outflow pipe connected to the evaporator are brought close to each other, and this adjacent part is housed in a sealed casing, and the above-mentioned 1. An air conditioner for an automobile, characterized in that condensed water from an evaporator is supplied into a sealed casing, and the refrigerant inflow and outflow pipes are arranged so as to be able to exchange heat with the condensed water.

(2) The air conditioner for an automobile according to claim 1, wherein the refrigerant inflow pipe is connected to the evaporator via an expansion valve.

(3) The air conditioner for an automobile according to claim 1, wherein the refrigerant inflow pipe and the refrigerant outflow pipe are arranged in contact with each other within a sealed casing.

(4) The air conditioner for an automobile according to claim 1, wherein the refrigerant inflow pipe and the refrigerant outflow pipe are twisted with each other so as to increase the contact area within the sealed casing.
