Title:
HEAT PUMP SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/185220
Kind Code:
A3
Abstract:
The invention relates to a heat pump system (1) having a refrigerant circuit (100) for generating heat, a primary feed line (701), a gas cooler (170) for the refrigerant circuit (100) and a return line (730) in which a heat transfer medium can flow, and an air-to-air heat exchanger (200). A pre-heater (270) is mounted in a flow direction (x) of external air flowing into the heat pump installation (1), said pre-heater being suitable for pre-heating external air (AU) to a minimum temperature value (tM) as required. The air-to-air heat exchanger (200) is mounted in a flow direction downstream of the pre-heater (270) and is suitable for the physically separate heating of the external air by means of exhaust air. An air heater (230) as the heat transfer medium-to-air heating unit is mounted in a flow direction (x) downstream of the air-to-air heat exchanger (200) and is suitable for adjusting the temperature of the external air to a supply air temperature (tGA).
