AI Technical Summary
Existing methods fail to effectively utilize waste heat generated by engines and convert mechanical energy from renewable sources like wind, waves, or water flow into usable heat without requiring continuous engine operation.
A method and apparatus that utilizes mechanical energy from wind, waves, or water flow to operate a compressor, generating heat through waste heat from a diesel engine, and uses a small additional compressor to regulate air pressure for controlled heat generation, employing a heat pump or absorption refrigeration machine for temperature adjustment.
Enables efficient heat generation and temperature control using renewable energy sources, providing consistent heat supply even in varying conditions, and allows for cooling in greenhouses and direct heat generation from sea waves.
Abstract
Description
[0001] The invention relates to a method and a device for generating heat.
[0002] Typically, mechanical energy is converted into electricity, and this electricity is used for various devices.
[0003] The invention is based on the objective of generating heat with minimal effort.
[0004] The problem underlying the invention is solved by a method according to claim 1 and a device according to claim 7. Advantageous embodiments are the subject of the dependent claims.
[0005] According to the invention, mechanical energy from wind, waves, or water currents is used to operate a compressor and to utilize the compressor's waste heat. If an engine, particularly a diesel engine, is used as the compressor, known devices can be employed to generate a significant amount of heat. The aim is thus to utilize the waste heat even when the engine is not running. This compressed air can also be enriched with fuel to operate the engine as a gasoline or diesel engine, depending on requirements, for example, when less mechanical energy is available.
[0006] If the air supplied to the compressor, which is compressed within the compressor, is controlled and preferably regulated, the amount of heat generated can be varied, for example, during constant rotation. This means that the pressure at which the air is supplied to the compressor is changed. Mechanical energy from wind, waves, or water currents can also be used to increase the pressure at which the air is supplied to the compressor. This can be achieved with a small additional compressor that, like a turbocharger, increases the pressure of the air supplied to the compressor. This allows the device to be easily controlled and preferably even regulated.
[0007] The generated heat can be used particularly efficiently with a heat pump. If cooling is required, an absorption chiller can also be used.
[0008] One possible application is a greenhouse with a wind turbine, where the turbine can generate heat for the greenhouse. Especially in strong winds, a greenhouse can easily cool down, which can be compensated for using the invention.
[0009] The wave motion on a larger lake or sea can also provide mechanical energy, for example via a float, which can be used to directly generate heat according to the invention. This also results in a significant amount of heat being provided during bad weather, which is usually associated with rougher seas.
