Abstract

The invention relates to a technique of ventilation and air conditioning. The aim of the invention is to increase the reliability of the device in operation and the degree of heat utilization during the cold period of the year. The device for utilization of thermal energy contains a heat exchange nozzle 2 located in the housing 1 with flow channels 3 and 4 of the heated and cooled gas streams communicated with the corresponding inlet and outlet nozzles 5, 6 and 7.8. The inlet and outlet nozzles 5 and 7 of the heated gas flow are additionally communicated with each other by means of a bypass duct 9 with an adjustable valve 10. The heat exchange nozzle can be made in the form of at least two sections 11 sequentially arranged in the housing 1 along the flow of the gas with the formation between them are intermediate chambers 12 with mixing elements 13. The bypass duct 9 has at least one additional nozzle 14 with an adjustable element 15 communicated from the side of flow channels 3 of heating About the gas flow with the corresponding intermediate chamber 12. 1 Il.

in the housing 1 along the flow of gas with the formation between them intermediate chambers 12 with mixing elements 13, the bypass duct 9 has at least one additional branch pipe 14 with an adjustable element 15 communicated from the flow channels 3 of the heated gas stream with a corresponding intermediate chamber 12 .1 il.

The invention relates to a technique of air implanting and conditioning.

The aim of the invention is to improve

reliability of work and degree of heat utilization in the cold period of the year.

The drawing shows a schematic diagram of a device for utilizing thermal energy.

The device for utilization of thermal energy contains a heat exchange nozzle 2 located in the housing I with flow channels 3 and 4 of the heated and cooled gas flows, which communicate with the corresponding inlet 5 and 6 and outlet 7 and 8 nozzles.

The inlet 5 and outlet 7 pipes of the heated gas flow are additionally communicated with each other by means of a bypass duct 9 with an adjustable valve 10.

The heap exchange nozzle 2 can be made in the form of at least two sections P (in this case, the nozzle 2 is made in the form of three sections P) sequentially arranged in the housing 1 along the gas flow with the formation of intermediate chambers 12 with mixing elements 1 3 between them. .

The bypass duct 9 has at least one additional nozzle 14 (in this case, the bypass duct 9 is made with two additional nozzles 14) with adjustable elements 15 communicated from the flow channels 3 of the heated gas flow with a corresponding intermediate chamber 12.

A device for utilization of thermal energy works as follows.

The cooled gas stream enters the device through the inlet 6, passes in the respective flow channels 4 of the heat exchange nozzle 2

releases its heat and is removed from the device through the outlet 8.

The heated gas flow enters the device through the inlet 5, passes through the respective flow channels 3 of the heat exchanger nozzle 2, is heated and then is fed to the consumer via the outlet 7.

At temperatures heated: o the gas flow, not causing the surface of the heat exchanging nozzle 2 to freeze on the side of the cooled gas flow, the adjustable valve 10 and the elements 15 are closed and the entire heated gas flow passes from the inlet 5 through the flow channels 3 to the outlet 7.

At a negative initial temperature of the heated gas flow, causing the surface of the heat exchanger nozzle 2 to freeze, a part of the heated gas flow as a result of corresponding controlled switchings of the valve 10 and the elements 15 enters the bypass duct 9. At the same time, a part of the heated gas flow from the inlet 5 enters the first course gas movement, section 1 of the heat exchanger nozzle 2, heats up and then enters the intermediate chamber 12, into which it simultaneously enters from the bypass duct 9 through an additional The steam nozzle 14 is part of the untreated heated gas stream, where both parts of the gas are mixed together by means of a mixing element 13,

The temperature of the resulting mixture of the heated gas stream does not cause the surface of the heat exchanger nozzle 2 to freeze with increasing flow rate of the heated gas stream through the subsequent section 11 of the heat exchanger nozzle 2.

Claims (1)

After the passage of this part of the heated gas flow through the second in the course of the movement section 11 and when performing the nozzle 2 with the number of sections 11, more than two, it is possible to do so much. The flow of gas with the maintenance of the operating mode of the device, in general, eliminates the possibility of frosting on the surface of the heat exchange nozzle from the flow channels 4 of the cooled gas flow. Invention Formula A device for utilization of thermal energy containing a heat exchange nozzle located in a housing with passage channels of heated and cooled gas flows communicated with corresponding inlet and outlet nozzles, the inlet and outlet nozzles of the heated flow gas is additionally communicated to metsi with the help of a bypass valve with an adjustable 11P valve, which is due to the fact that, in order to increase the reliability of operation and the degree of heat utilization in the cold period of the year, the heat exchange cap is complete in the form of at least two sections, successively located in the housing along the flow of gas with the formation of intermediate chambers with mixing elements between them, and the air duct is provided with at least one additional pipe with an adjustable element communicated from the flow channels of the heated gas flow with the corresponding intermediate chamber.
