Method and device for several small houses

Abstract

Disclosed is a system for heating and cooling, respectively, of more than one house, where at least two houses are connected to a common energy storage in the ground and where a control device is arranged to transport a heat carrier in a pipe work connected to the energy storage. The houses are connected in parallel in relation to each other to the pipe work. Certain of the houses are arranged to exploit the heat carrier for cooling by raising the temperature of the exploited heat carrier with about 3-4° C. at the same time as other houses exploit the heat carrier for heating by lowering the temperature of the exploited heat carrier with about 3-4° C. The common heat storage is arranged so that the heat carrier flowing out from the common energy storage holds an approximatively constant temperature. A related method is also disclosed.

         3 . System according to  claim 2 , wherein at least one of the heat pump devices arranged in the houses is or are arranged to selectively be able to generate heat or coldness for local use in the house in the form of heating of indoors air and/or tap water or cooling of indoors air. 
     
     
         4 . System according to  claim 2 , wherein the respective heat pump devices of certain of said houses are arranged to exploit the heat carrier flowing therethrough for cooling, at the same time as the respective heat pumps of other houses exploit the heat carrier flowing therethrough for heating. 
     
     
         5 . System according to  claim 4 , wherein the respective heat pump devices of said certain houses are each arranged to exploit the heat carrier flowing therethrough for cooling or heating, independently of a mode of operation of the respective heat pump devices of other houses. 
     
     
         6 . System according to  claim 1 , wherein the pipe work is in the form of a closed system in which the heat carrier is arranged to be transported. 
     
     
         7 . System according to  claim 1 , wherein said approximately constant temperature is substantially the mean annual temperature for the geographical location at which the system is installed. 
     
     
         8 . System according to  claim 1 , wherein the number of houses that are connected to the energy storage is between 10 and 100. 
     
     
         9 . Method for heating and cooling, respectively, of more than one house, where at least two houses are connected to a common energy storage in the ground and where a control device transports a heat carrier in a pipe work connected to the energy storage, wherein the houses are connected in parallel in relation to each other to the pipe work,
 wherein certain of said houses exploit the heat carrier for cooling by raising the temperature of the exploited heat carrier with about 3-4° C. at the same time as other houses exploit the heat carrier for heating by lowering the temperature of the exploited heat carrier with about 3-4° C., and   wherein the heat carrier flowing out from the common energy storage holds an approximatively constant temperature.   
     
     
         10 . Method according to  claim 9 , wherein the houses are each arranged with a separate respective heat pump device connected to the pipe work such that said heat carrier flows through the heat pump device, which heat pump devices perform said heating or cooling. 
     
     
         11 . Method according to  claim 10 , wherein at least one of the heat pump devices arranged in the houses selectively generates or generate heat or coldness for local use in the house in the form of heating of indoors air and/or tap water or cooling of indoors air. 
     
     
         12 . Method according to  claim 10 , wherein the respective heat pump devices of certain of said houses exploit the heat carrier flowing therethrough for cooling, at the same time as the respective heat pumps of other houses exploit the heat carrier flowing therethrough for heating. 
     
     
         13 . Method according to  claim 12 , wherein the respective heat pump devices of said certain houses exploit the heat carrier flowing therethrough for cooling or heating, independently of a mode of operation of the respective heat pump devices of other houses. 
     
     
         14 . Method according to  claim 9 , wherein the pipe work is in the form of a closed system in which the heat carrier is transported. 
     
     
         15 . Method according to  claim 9 , wherein said approximately constant temperature is substantially the mean annual temperature for the geographical location at which the system is installed. 
     
     
         16 . System according to  claim 2 , wherein several of the heat pump devices arranged in the houses is or are arranged to selectively be able to generate heat or coldness for local use in the house in the form of heating of indoors air and/or tap water or cooling of indoors air. 
     
     
         17 . System according to  claim 2 , wherein all of the heat pump devices arranged in the houses is or are arranged to selectively be able to generate heat or coldness for local use in the house in the form of heating of indoors air and/or tap water or cooling of indoors air.
