Combined trigeneration systems
Basic information
Combined trigeneration systems allow simultaneous production of electric energy, thermal energy and chill energy based on a single source of primary energy. Due to the possibility to utilise waste heat, they are economic in operation and environment-friendly.
Combined trigeneration systems are characterised by high design and structural flexibility. Depending on needs, they are built on the basis of:
- various engine types (gas, Diesel)
- various fuel types (natural gas, landfill gas, mine gas, waste gas, LPG, biogas, diesel oil…)
- different unit types (ADsorption, bromolithium absorption, ammonia absorption, compressor)
- different types of heat sources supplying the units, including natural energy and waste heat
- different building-in options (stationary, mobile)
As a result of that, these systems can be implemented in many different types of objects. They guarantee efficient management of generated thermal energy throughout the year (also on the 24h-per-day basis), and thus obtaining measurable benefits.
Versatile use
Combined trigeneration systems are a desirable option wherever there is a demand for electric, thermal and chill energy.
Owing to flexibility in selection of solutions, the investment project is economically justified regardless of object size, type and intended use.
Combined trigeneration systems can be successfully implemented in large special purpose facilities:
- industrial plants, production halls
- facilities including refineries, mines, power plants, petrol stations…
- facilities including airports, bus/railway stations
- storage facilities and rooms
- hospitals and medical facilities (surgeries, treatment rooms…)
- technological facilities (server rooms, UPS, data centre…)
- telecommunication facilities
- separated urban areas (a system connecting several buildings)
Combined trigeneration systems can be also scaled for the purposes of more typical buildings:
- central administration facilities
- public buildings
- office buildings
- service facilities
- commercial and conference centres
- large-format stores
- hotels, restaurants, wellness facilities
- residential buildings
Measurable benefits
First of all, combined trigeneration systems provide measurable economic benefits - also after having included the required level of investment outlays.
Substantial optimisation of facility operating costs and costs of its operating activity can be achieved through:
- reduction of primary fuel consumption while reaching the same energy performance
- reduction of running facility operating costs
- reduction of running system operation costs (monitoring, maintenance, servicing)
- waste heat use
- simultaneous production of heat and chill
- stable and independent energy supply source
- reduction of losses generated by power stoppages
- reduction of losses generated by energy transmission
- selling surplus electric energy to power grid
- up to 50% compared to the amount of fuel required when using 3 independent supply systems for electric, thermal and chill energy.
Moreover, investor gains considerable image-related benefits through:
- improved facility standard
- higher building use comfort
- reduced emission of greenhouse gases and other noxious substances
- employing proecological solutions friendly for local community
- investment in agreement with the requirements of international proecological directives and standards
Zechik – optimal return on investment
Combined trigeneration systems constitute a highly flexible solution, which can be effectively designed according to Clients’ individual needs.
As a result of wide range of equipment and many system configurations available, each system will differ in efficiency and investment outlays. The final form of each system is obtained after a detailed analysis of energy and economic efficiency of a project.
Finding an optimal solution satisfying specific requirements is a time-consuming and complicated process. Vast knowledge and many years of our design team’s experience allow us choosing the most suitable equipment and designing a system that meets specific demands taking into account the most recent engineering knowledge and high economic efficiency.
