Arrangement for air conditioning rooms and heat pump unit for use in the arrangement

摘要

The invention relates to an arrangement for air-conditioning rooms and to a heat pump for use in such an arrangement. The arrangement comprises a central heating device, to which multiple lines containing a heat-exchanging fluid are connected. The arrangement additionally comprises multiple decentralized, electrically operated heat pump units, which are energetically connected to the central heating device via the mentioned lines. The respective heat pump unit has a plurality of heat pump modules, which absorb thermal energy from the fluid for heating or deliver thermal energy to the fluid for cooling and/or dehumidifying. The mentioned heat pump modules preferably comprise Peltier elements acting as heat pump elements.

主权项

1. A heat pump unit, comprising
a housing, the housing including walls and a front plate and having first openings and second openings, heat pump modules each including one or more thermoelectrically operating Peltier elements and one or more cooling modules connected to the one or more Peltier elements, the cooling module having an inlet and an outlet for a heat exchanging fluid, and a fan, wherein the heat pump modules and the fan are arranged in an interior of the housing, the fan is configured to pull air through the first openings, convey the air to the heat pump modules and blow the air through the second openings, by supplying electrical energy to the heat pump modules, the heat pump modules in a heating mode withdraw heat energy from the fluid and deliver the withdrawn heat energy to the air passing by, and in a cooling mode withdraw heat energy from the air passing by and deliver the withdrawn heat energy to the fluid, the front plate is a boundary of the housing having an outer face configured to be in contact with the air in a room and an inner face configured to be in direct contact with at least one of the one or more Peltier elements in order to emit in the heating mode heat energy withdrawn from the fluid by the at least one of the one or more Peltier elements via the front plate as thermal radiation directly into the room.
