A ventilation and air conditioning apparatus (1), comprising an air intake apparatus (10), an air exhaust apparatus (20), and an air conditioning unit (30). The air intake apparatus is configured to, in an installed state of the ventilation and air conditioning apparatus, define an intake flow path (IFP) from an environment (E) of a confined space (CS) to the confined space. The air exhaust apparatus is configured to, in the installed state of the ventilation and air conditioning apparatus, define an exhaust flow path (EFP) from the confined space to the environment of the confined space. The air conditioning unit comprises a first heat exchange unit (32) and a second heat exchange unit (34), which are coupled to each other via a refrigerant circuit comprising a refrigerant. The first heat exchange unit is configured to transfer heat between the intake air in the intake flow path and the refrigerant. The second heat exchange unit is configured to transfer heat between the refrigerant and the exhaust gas in the exhaust flow path and the refrigerant. An entertainment vehicle, such as a camper, a cart, or a mobile house, having a ventilation and air conditioning apparatus. The ventilation and air conditioning apparatus has higher energy efficiency.
