System for Extracting Heat from Outside Air

Abstract

The present invention relates to a system for extracting heat from outside air. The system comprises a feed connecting to outside air, a heat exchanger connected to the feed and a discharge connecting to the heat exchanger and outside air, and a channel connecting the feed, the heat exchanger and the discharge. The system herein further comprises an impeller associated with the channel for providing a volume flow of outside air sufficient for the heat exchanger via the feed and along or through the heat exchanger. The system according the invention is distinguished from existing systems, which make use of noisy fans as impellers, in that the channel comprises an upright ascent pipe, an upright descent pipe and a connecting pipe between the ascent pipe and the descent pipe. The heat exchanger is connected here to the descent pipe. A sufficient airflow can thus be initiated/maintained for an effective operation of for instance the evaporator of or at a heat pump.

 a feed connecting to outside air;   a heat exchanger connected to the feed;   a discharge connecting to the heat exchanger and outside air;   a channel connecting the feed, the heat exchanger and the discharge;   an impeller associated with the channel for providing a volume flow of outside air sufficient for the heat exchanger via the feed and along or through the heat exchanger wherein:   the channel comprises an upright ascent pipe, an upright descent pipe and a connecting pipe between the ascent pipe and the descent pipe; and   the heat exchanger is associated with the descent pipe.   
     
     
         2 . The system as claimed in  claim 1 , wherein a heater is provided which is substantially associated with the ascent pipe. 
     
     
         3 . The system as claimed in  claim 1 , wherein the ascent pipe and the descent pipe both extend substantially upward from the connecting pipe, and the heater is substantially associated with at least one of the ascent pipe and the connecting pipe. 
     
     
         4 . The system as claimed in  claim 1 , wherein the ascent pipe and the descent pipe both extend substantially downward from the connecting pipe, and the heat exchanger is substantially associated with at least one of the descent pipe and the connecting pipe. 
     
     
         5 . The system as claimed in  claim 1 , wherein a heat pump is connected to the heat exchanger. 
     
     
         6 . The system as claimed in  claim 5 , wherein a storage tank is associated with the heat exchanger and the heat pump. 
     
     
         7 . The system as claimed in  claim 2 , wherein the heater is associated with at least a considerable part of a length of the ascent pipe. 
     
     
         8 . The system as claimed in  claim 7 , wherein the heater is associated with substantially the whole length of the ascent pipe. 
     
     
         9 . The system as claimed in  claim 1 , wherein the heat exchanger is associated with at least a considerable part of a length of the descent pipe. 
     
     
         10 . The system as claimed in  claim 9 , wherein the heat exchanger is associated with substantially the whole length of the descent pipe. 
     
     
         11 . The system as claimed in  claim 2 , wherein the heater is at least one of the elements or components from the group comprising: fuel cells, electric heating elements or any other heater. 
     
     
         12 . The system as claimed in  claim 11 , with a heater in the form of a fuel cell, wherein a gas container is provided for containing a buffer supply of gas required by the fuel cell. 
     
     
         13 . The system as claimed in  claim 11 , further comprising an electrolysis unit for providing the fuel cell with hydrogen and/or oxygen gas required thereby. 
     
     
         14 . The system as claimed in  claim 1 , further comprising a solar collector for generating electric power required by the system from solar energy. 
     
     
         15 . The system as claimed in  claim 1 , further comprising a heat exchanger connected to the feed and the discharge for recovering heat from discharge air.
