  • compressed refrigerant gas, compressed air, and mechanically heated hot water is produced and stored during off-peak hours when electricity prices are lower.
  • These stored resources are then used in the manner described above to reduce the HVAC system(s)' demand for electricity during peak hours when electricity is more expensive.
  • this embodiment can serve to both reduce electrical demand in peak hours, potentially lowering peak electrical demand from the electrical grid, and also to lower the operating costs.
  • Using stored resources in this manner is suited to locations where it is not feasible to operate wind turbines such as in dense urban localities.
  • wind powered system 10 for the direct mechanical powering of systems comprising energy stores is shown and is generally identified by reference numeral 10.
  • wind powered system 10 comprises a wind turbine 12 mechanically coupled to a plurality of systems generally identified by reference numeral 14.
  • wind turbine 12 comprises a plurality of blades 20 mounted on a hub 22.
  • the leading edges of the blades 20 may be conventional or employ tubercles as described in International PCT Application No.
  • the hub 22 is affixed to one end of a rotor shaft 24.

  • the transmissions 44 may comprise suitable mechanical, magnetic, pneumatic and/or hydraulic linkages to translate rotation of the ring gear 42 to the systems 14.
  • wind directed at the wind turbine 12 causes the blades 20 to rotate the hub 22 which in turn imparts rotation of the rotor shaft 24.
  • Rotation of the rotor shaft 24 is translated to rotation of the vertical drive shaft 26 via the drive gear 32 and pinion 34 of transmission 30.
  • Rotation of the vertical drive shaft 26 in turn rotates the ring gear 42.
  • Rotation of the ring gear 42 is translated to the systems 14 by the transmissions 44 thereby allowing the wind turbine 12 to power the systems 14 through direct mechanical coupling.

  • the HVAC heat pump compressor 50 is connected to a suitable storage tank 60 via gas connections 62.
  • the closed refrigerant gas cycle is supplied with a significantly larger quantity of refrigerant gas for circulation than would be available in a conventional heat pump. Operation of the heat pump compressor 50 through powering by the wind turbine 12 provides for an extra quantity of compressed refrigerant gas that is stored in the storage tank 60 for use during normal heating or cooling operations of the HVAC heat pump.
  • the gas represents, in effect, a form of stored energy because it has been produced by the heat pump compressor 50 and has the particular advantage that it can be stored in the storage tank 60 and used when required with virtually no additional required energy expenditure. This is particularly advantageous when wind power, which is inherently intermittent, is not available. Whether there is wind or not, requisite quantities of compressed refrigerant gas can be released from the storage tank 60 under the control of electromechanical or electromechanical/pneumatic means (not shown) and allowed to pass through the connections 62 in the closed refrigerant gas cycle to an expansion valve (not shown) and then into a heat exchanger 64 where it can be used for cooling in the normal manner.
  • the HVAC heat pump operates in its air conditioning mode in a normal fashion when wind energy is available and uses gas which has been previously compressed when wind energy is not available, hi the heating mode, the HVAC heat pump releases heat during the compression operation, hi this case, a connection to a heat store in the form of an insulated storage tank 66 filled with water is provided to allow the heat to be stored for later use.
  • the mechanical heater 52 is of the turbulence type and converts mechanical energy into heat by heating water when powered by the wind turbine 12 to a temperature of up to 38O°F.
  • the mechanical heater 52 is connected to the insulated storage tank 66 via suitable connections 72 so that the hot water can be stored until it is supplied to the heat exchanger 64 as a supplemental source of heat.
  • the heated water is exchanged via the heat pump. In this manner, sufficient energy can be available for heat exchange even when sufficient heat is not available from the air.
  • the hot water may be generated during those periods when wind energy is available and stored in the storage tank 66 for later use when there is a decline or absence of wind.
  • the heated water in the storage tank 66 can be applied to an expander (not shown) in order to generate steam which can then be used to power a steam turbine in order to generate electricity. While steam derived from water at this temperature is typically not suitable for powering steam turbines, if the blades of the steam turbine employ tubercles as described in the above-incorporated PCT application, the steam turbine can be effectively powered by the steam. This is due to the fact that the tubercles on the steam turbine blades allow for the extraction of energy from low speed fluid flows with greater efficiency.
  • the air compressor 54 is connected to a suitable storage tank 80 by pneumatic connections 82 in such a manner that when powered by the wind turbine 12 quantities of compressed air can be accumulated in the storage tank 80 and distributed via an electromechanical control device 84 to compressed air lines in order to pneumatically power various devices forming part of the HVAC heat pump, parts of the wind turbine itself, including but not limited to pumps, fans, and vents (not shown), or the motor 40 and pinion yaw gear 42 which controls the orientation of the wind turbine blades 20 relative to the wind.
  • the electrical generator 56 when powered by the wind turbine 12 converts the mechanical energy into electricity. Provided with suitable electrical connections (not shown) the output of the generator 56 provides electricity for operation of pumps, fans, lights, etc.
  • the various systems 14 can be configured in different ways for different applications and thus, tailored to operation in cold climates, remote locations distant from an electrical grid or for HVAC applications in large urban buildings.
  • suitable connections might be made in a remote location so that the electrical generator 56 can be pneumatically powered by compressed air when wind is not available, while such means might be deemed too expensive in an urban setting where access to the electrical grid is readily available.
  • devices such as the fans and pumps required to operate the HVAC heat pump air handler and ventilation system (not shown) with electricity from the electrical generator 56 or by compressed air from the air compressor 54 and/or its associated storage tank 80.
  • the wind turbine 12 is preferably scaled relative to the demand so that it will produce a sufficient oversupply of mechanical energy when wind is available to serve all of the stored energy requirements.
  • each individual site at which the system 10 is to be installed should be evaluated with respect to prevailing winds, mean wind speed and a detailed estimation of the availability of wind in terms of seasons, days and even hours of the day. This assessment should also account for the specific turbine efficiency, the height of the support tower 28 etc. so that a sufficient amount of surplus energy is available from the systems 14 during times when inadequate wind power must be supplemented.
  • the systems 14 should have a capacity to store enough energy to continue uninterrupted operations for a period of approximately 30% longer than the projected longest period of interruption.
  • the wind turbine 12 may also be scaled to provide a surplus of mechanical energy to one or more compressors such that each compressor can produce all of the compressed gas required for air conditioning or for pneumatic power plus an appropriate surplus of compressed gas which can be stored for use when winds either fall or fail. While small scale deployment is discussed, it should be noted that it can be readily scaled up (either directly or in parallel) to serve larger systems. It should be noted that the compression and storage of surplus quantities of air conditioning gas provides an alternative means of energy storage. Indeed, in technical terms, it is not so much an energy storage device as a stored resource. It is well known in the art that heat pumps, whether employed for heating or cooling, do not generate heat or cooling except as an incidental byproduct, hi particular, compressing the gas forces the gas to give off heat.
  • the HVAC heat pump may be employed to heat or cool buildings as desired by either pumping heat out of a building and releasing it into the air or the ground for cooling, or by collecting heat from the air or ground and releasing it as heat inside the building.
  • the wind powered system 10 discussed above uses low grade energy to power work directly and then stores the product of that work whether as hot water or compressed gas, in a form which can be employed directly to accomplish work.
  • the wind powered mechanical system 10 efficiently uses low grade mechanical energy to do work directly and stores the surplus work product as low grade energy (mechanically heated hot water) or compressed gases (such as Freon or compressed air) for use when the mechanical energy from the wind is insufficient.
