  • a control unit compares a temperature of the engine detected by a temperature sensor with a plurality of different predetermined values, and based upon results of the comparison, controls the electric motors for driving the cooling fans in such a manner that as the detected temperature is higher, the flow rate of cooling air flowing in the engine room is larger.
  • the control unit is operable when an abnormality occurs in sensors for sensing operating conditions of the engine, for operating the electric motors to drive the water pump and cooling fans.
  • an analog circuit is operable when an abnormality occurs in the control unit, for operating the electric motors to drive the water pump and the cooling fans.

  • joinder references e.g ., attached, affixed, coupled, engaged, connected, and the like
  • joinder references are only used to aid the reader's understanding of the present disclosure, and may not create limitations, particularly as to the position, orientation, or use of the modules/ devices and/or methods disclosed herein.
  • Such joinder references are to be construed broadly.
  • joinder references can infer that two elements or modules are not directly connected to each other.
  • an intercooler 206 is typically configured to cool down heated high-pressure air supplied from a turbocharger while a cooling jacket 214 is configured to extract large amounts of heat from an engine 106 in order to cool down the engine 106. Therefore, it can be assumed that an operating temperature of an intercooler 206 is typically less than an operating temperature of the cooling jacket 214. Accordingly, with reference to the present disclosure, the first cooling circuit 202 (associated with the intercooler 206) may be regarded as a low temperature circuit; while the second cooling circuit 208 (associated with the cooling jacket 214) may be regarded as a high temperature circuit.
  • fluid present in the first cooling circuit 202 can travel between the intercooler 206 and the first heat exchanger 204 so as to cool the intercooler 206.
  • fluid present in the second cooling circuit 208 can travel between the second heat exchanger 210 and the cooling jacket 214 associated with the engine 106 so as to cool the engine 106.
  • an ambient temperature T i.e., temperature of atmospheric air taken from outside of the container 102, or a temperature T1 of air within the engine room 104 is lower than a pre-defined threshold value that is required at the intercooler 206, then a temperature of charge air supplied to the engine 106 would become low.
  • Such low ambient temperature T or low temperature T1 of air within the engine room 104 can therefore, affect an overall performance and power output from the engine 106.
  • the controller 226 may direct the diverter valve 224 to open thereby allowing some fluid from the second cooling conduit 212 (part of the second cooling circuit 208 i.e ., high temperature circuit) to enter the first cooling conduit 205 (part of the first cooling circuit 202 i.e., the low temperature circuit).
  • This allows heat transfer to occur at first cooling circuit 202 i.e., at the first heat exchanger 204 until the temperature T1 of air within the engine room 104 at a charge air inlet of the engine 106 attains a value that is conducive for optimal combustion performance of the charge air-fuel mixture at the engine 106.
  • the air comes in contact with the first heat exchanger 204 before entering the engine room 104.
  • the entering air gets heated to an elevated temperature as fluid present in the first heat exchanger 204 (part of first cooling circuit 202) is hotter than the ambient air entering the container 102 or the engine room 104.
  • temperature T or T1 of air that is entering the engine room 104 can be increased i.e., regulated to an optimal value so as to assist the combustion performance of the engine 106.
  • the fluid is portioned from the first cooling circuit 202 after the first heat exchanger 204 and may be interspersed back with the fluid in the second cooling circuit 208 for e.g ., after the cooling jacket 214 (as shown in FIG. 2 ) or after the second heat exchanger 210 (as shown in FIG. 3 ).
  • the temperature T1 of air within the engine room 104 can be beneficially regulated by using a difference of temperatures of fluids present within the first cooling circuit 202 and the second cooling circuit 208 respectively. It is hereby envisioned that with use of embodiments disclosed herein, manufacturers of power generating systems can also do away with the use of conventional air ducts, baffles, and/or columns in the containers that are known to be tedious and expensive to install and/or operate. Moreover, in some cases, enclosures may typically offer tightly constrained spaces for installation and fitment of components. However, an implementation of embodiments disclosed herein can help manufacturers reclaim valuable space within such tightly constrained enclosures.
  • the temperature T1 of air within the engine room 104 can become greater than the ambient temperature T of air i.e., T1 > T. Therefore, for purposes of the present disclosure, the temperature T1 of air entering the engine room 104 can be regarded as being substantially equal to the ambient temperature T of air i.e., T1 ⁇ T initially, and thereafter, with the help of embodiments disclosed herein, become greater than the ambient temperature T of air i.e., T1 > T.
  • the temperature T1 of air within the engine room 104 is increased until the temperature T1 reaches an optimum value corresponding to optimal combustion performance parameters at the engine 106 and/or facilitates maximum heat rejection efficiency to occur at the first and second cooling circuits 202, 208 when the circuits 202, 208 finally reject heat into the air present within the engine room 104.
  • the controller 226 is capable of regulating the diverter valve 224 and the control valve 230 in a simultaneous manner or a tandem manner.
  • the controller 226 may also be configured to perform the regulation of the diverter valve 224 and the control valve 230 independently of each other without deviating from the scope of the present disclosure.
