PREAMBLE OF THE INVENTION
The following specification describes the nature of the invention and the manner in which it
is performed.
FIELD OF THE INVENTION
The present invention relates to a portable integrated power pack system of energy generation and its utilization using renewable energy sources like solar power, wind energy, etc. as the main power source and direct current diesel generator / battery bank as an alternate power sources. The system utilizes waste heat from direct current diesel generator to meet the energy and power needs in remote areas for shelters, cabinets, houses for space and water heating and/or cooling as like but not restricted to power needs only in the remote areas.
In particular, the present invention relates to an integrated hybrid power generator and environment conditioner system that utilizes renewable energy sources, energy storage means and variable speed Direct Current Diesel Generator (DCDG) as power sources and Waste Heat Recovery System (WHRS), Air handling unit and heaters as environment conditioners.
BACKGROUND OF THE INVENTION
Most remote communities around the world today are dependent on fossil fuels for most of their energy requirements. These communities are exposed to diesel fuel price volatility, frequent fuel spills and high operation and maintenance costs including fuel transportation and bulk storage. With a boom in industrialization, demand for reliable and sustainable power is the need of the hour. Power systems that cater to power requirement at easily accessible locales have been considerably addressed. However, power generation at remote, difficult to access locales remains a cause for concern. In addition to remote area power systems, commercial and residential customers in urban areas are also seeking new sources of backup power located on their premises. Diesel generators are typically used as a major source of backup power in the remote location or the urban areas. However, transportation of generator sets, increased fuel consumption, rising cost of fuel, increased emission and noise pollution are some of the major concerns faced when using Diesel Generators. In the past few decade diesel
prices have been increased more than doubled. High fuel costs have translated into tremendous increases in the cost of energy generation. Accordingly, operating costs of such power systems is very high.
Renewable energy sources such as photovoltaic are clean, affordable, readily available, and sustainable and can supplement generators in both grid and off- grid residential and commercial applications. Hybrid energy systems integrate the renewable energy technologies with the diesel generators, inverters and batteries to provide grid quality power in remote areas which are not connected to a utility grid.
There are two possible approaches for supplying electricity to remote areas: grid extension and the use of diesel generators. The grid extension can be a very expensive option in many locations. Therefore, the diesel generators are only viable option for electrification in the remote area. However the main problems of remote area power generation using diesel generators are air and noise pollution, transportation, loss in diesel fuel efficiency and increased operation and maintenance cost due to incomplete combustion of fuel during light loads and loss of heat generated during its operation. Also, the transportation and fuel prices are a major concern at high altitudes and at remote places where the prices varies from four times to six times as compared to local fuel and transportation prices.
With a view, therefore, to overcome the problems associated with the use of conventional resources such as fossil fuels, diesel, and petrol etc the inventor's felt the need to develop a hybrid system that utilizes the heat energy of generator, harness the non conventional sources of energy like solar energy, wind energy, etc. There are number of applications where this hybrid power generator can be used such as remote villages, islands, houses, cabins, shelters, or more specifically at high altitude and/ or remote place shelters, for water heating, space heating and/or cooling inside the shelters. The use of said system increases engine life and reduces noise pollution and consumption of exhaustible natural energy resources. Also, said system is reliable, cost effective and fuel efficient.

SUMMARY OF THE INVENTION
The integrated hybrid power generator and environment conditioner comprises of a
variable speed direct current diesel generator (DCDG), a hybrid controller, solar and/ or wind power source, waste heat recovery system, battery bank, alternating and direct current heating systems. The fuel cost of variable speed DCDG contributes 60 to 70 percent improvement in operation cost. The ioad on the DCDG varies based on ambient temperature and load requirements. The variable speed concept saves about 15 to 25 percent of fuel, thereby reducing the carbon monoxide emission. The hybrid controller is an important assembly for the system. It is used for power management and integration. The main objectives of the controller are to minimize the operating costs for the variable speed DCDG, provide an optimistic energy solution for the hybrid system, and appropriate utilization of energy sources thereby moving a step ahead towards the green environment. The renewable energy i.e. solar and/ or wind are the priority source of power for the hybrid system. The photovoltaic/ Copper Indium Gallium Selenide (CIGS) technology of the flexible panels are light weight, with no heat and reflection signature thereby assuring maximum solar energy absorption. In a preferred embodiment, the renewable energy source used is solar power which herein is a primary power source. The waste heat recovery system is designed to recover the heat energy from the hot flue gases / hot waste gases of the variable speed DCDG and utilize it for domestic and /or industrial applications. This system has key components like insulated waste heat recovery system, mild steel hot water tank, water recirculation system, primary and secondary heat exchanger and air handling unit and control panel.
The operational logic for the hybrid system is described as follow. The variable speed direct current diesel generator (DCDG) is the base power source. The variable speed DCDG is kept in an auto mode and the miniature circuit breaker of the variable speed DCDG is switched on to connects rectifier to load. Also, the miniature circuit breaker of the control panel and of the hybrid controller is switched on. When the inverter, miniature circuit breaker of solar, load and battery are switched on, solar power starts charging the battery bank. The voltage of the battery bank is checked at regular intervals to ensure the battery performance and to increase its life.
The solar power is provided by means of flexible photovoltaic cells. As herein, if solar power is unavailable, then it will check for the wind power source. These powers from non conventional sources are utilized for charging the battery bank as well as catering the DC and AC auxiliary loads. In case, if solar power and / or the wind power sources are unavailable or the load demand increases beyond the solar power and / or wind power source capacity, then the hybrid controller starts the variable speed DCDG. The excess load is catered by the variable speed DCDG. When the load demand decreases and is within the capacity of solar power source, the hybrid controller automatically shuts down the variable speed DCDG. The waste heat produced from the operation of variable speed DCDG is utilized for water heating/ cooling and /or space heating/ cooling and other general usage purpose. The primary heat exchanger is preferably fitted and positioned horizontally with the insulated mild steel water tank. The mild steel water tank is filled with fresh and clean water with adequate water supply to the waste heat recovery system to prevent the dry run of the waste heat recovery system. Exhaust flue gases are directed from the DCDG to the waste heat recovery system through flexible pipes. The water in the water tank enters into the waste heat recovery system which recovers thermal energy from hot flue gases / hot waste gases and transfers to the surrounding water in the waste heat recovery system. The primary side and secondary side centrifugal pumps maintains required velocity in the system through air handling unit and secondary heat exchanger in closed loop and facilitates uniform heat distribution in the water with the help of modulation of air temperature sensor and three way modulating valve for hot water. Also care is to be taken that air must be removed from in water pump by loosening the main screw so as to avoid air bubbles in water pipe and to have continues flow of water in WHRS. The control panel incorporates relay switches which controls operation of the primary as well as secondary side water circulation pumps, air modulating sensor, level switch & three way modulating valve. After ensuring that the AC miniature circuit breaker is on, the AC loads are switched on for further applications such as floor heaters, lighting, heating, and cooling but not restricted to the same. The solar power can be utilized for the entire day and can supply power for five to eight kilo watt hours per day.
The integrated hybrid power generator and environment conditioner concentrates on providing energy by the following three ways:
a) Efficient usage of all power sources through an integrated power generator system specifically by utilizing the waste hot gases produced from the DCDG.
b) Optimum fuel savings through an integrated hybrid power generator system by utilizing the renewable resources.
c) Ease in transportation, by reducing down the size of the DCDG.

10. A method of operating integrated hybrid power generator and environment conditioner system for providing AC and DC power in extreme environmental conditions comprising the steps of:
- generating power by nonconventional sources of energy (primary source) (10) for charging a battery bank (16) as well as catering the DC and AC auxiliary loads (20) and (22) respectively of the hybrid system;
- estimating the power generated by nonconventional sources of energy (primary source) (10) through power measuring devices;
- estimating load connected to the hybrid system through Electronic Control Unit (ECU) (14);
- comparing the generated power with the estimated load by ECU (14) and if the power generated is less than the estimated load then ECU will send command to automatically start secondary source (12) for supplying the required power to the hybrid system;
- providing start command repeatedly by the ECU (14) to the secondary source (12) in case the secondary source (12) fails to start automatically in first command;
- generating audio visual alarm by the ECU (14) indicating "Auto Start failure" and to start the secondary source (12) manually with the help of Manual Start Push Button provided on its control panel;
- shutting down the secondary source(12) by ECU (14) when the load demand of the hybrid system decreases and it is within the capacity of the primary source (10);
- converting the DC output generated by the secondary source (12) to the AC by the inverter (18) for supplying power to the AC load;
- checking the availability of the primary source (10) and the secondary source (12) continuously; and
- supplying the power from the charged battery bank if both primary (10) and secondary (12) sources are not available.
