Use of Natural Gas Engines for Water Chillers, Heat Pump Machines and VRV Systems
Giorgio Raptis
Tecnocasa
Italy
Natural gas can be used as an energy source to propel air conditioning systems in a reliable, inexpensive way using rotating gas engines compressors in direct expansion. Units of this type can be used for water cooling or as heat pumps also for heating at high outputs and with high efficiency. The units can also be used as a key component in direct-type climbing systems VRV.

Israel
Education: MSc degree in electromechanical engineering from Polytechnic Institute Iași in Romania, 1976.
Professional Background:
Project Manager and Chief Engineer at Y.Uspiz electrical motors.
Manager of electrical and control department of the National Water Carrier of Mekoroth.
Chief engineer of the electrification project of Israel Railway.
Chief Electrical Engineer at EAPC.
Member of technical committees of the Israel Standards Institution.
Member of the High Engineering Board of the SEEEI.
The motives for converting to gas for the establishment of a gas energy center are the regulatory requirement for the Ministry of Environmental Protection's nooks and crannies and the need for energy efficiency and energy expenditure vaccination.
The heat center of Hadassah Hospital in Jerusalem operates on fuel oil and the only way to maintain the level of knocks as required by the regulator is to use a high-cost emulsion facility.
The conversion to cogeneration enables the transition to fuel-friendly, the production of all energy inputs in one place, considerable savings and the renewal of infrastructure.

Calculation of the electrical power required from the station in order to supply the full energy needs, electricity, heat and cold.
Examination of the technical and regulatory implications of a station of this size:
Connection to the distribution franchisee.
High voltage network connection.
The regulation of stations with a power of up to 5MW and the regulation for a station with a power greater than this.
Seizure of required land and solution of statutory problems.
Examining whether there is an entrepreneurial viability to submit a bid for the tender.
Writing the technical chapters for the tender.

Co-generation as a means of energy efficiency
Nahum Rapoport
Consulting
Israel
In 1967 he graduated from the Polytechnic Institute in Chisinau, a former USSR major in electrical engineering with a specialization in control systems and remote control. In 1997 he moved to gas power turbines to the position of operations engineer, deputy and deputy station manager.
In 2005, he was appointed director of power plants and combined cycle gas turbines and served in this position until his retirement in 2010.
Currently engaged as an independent engineering consultant in the field of gas turbine power plants, combined cycle units and co-generation units. Since 2013, he has also been the head of technology at Bar-Dov Engineering and Management, a company that deals with, among other things, co-generation.
With the entry of Israel into the era of natural gas and the transfer of a large part of the electricity production in the gas operation system, came a second phase of the natural gas revolution in Israel - the phase of decentralized production Through co-generation. Co-generation is a process that combines electricity generation at the point of consumption using gas turbines or gas engines and heat and / or cold generation using residual heat emitted from the machines that generate electricity. In the case of simultaneous production of cold and heat, the process is called three-generation. The efficiency of co-generation systems may reach 85%, for comparison, the efficiency of the most efficient units of integrated recycling in the country, seawater-cooled units reaches% (57 ÷ 58). Production in co-generation units instead of power consumption prevents transmission losses.
In Israel, more than 50% of the electricity consumption of home consumers, offices, hotels, hospitals, businesses is consumed by air conditioning systems. Due to the climate in the country most of the air conditioning is cooling. But if the cold water for air conditioning is produced by means of absorption chillers operated by residual heat and not by electric chillers, the power consumption can be significantly reduced.
This is the energy efficiency!
The choice of co-generation facilities depends on many factors and in particular, the needs of each and every consumer. Therefore, before deciding on the size and type of co-generation facility and in particular, the type of facility that operates a generator for power generation, gas engine or gas turbine, a careful analysis of needs must be performed, such as: the amount of electricity consumed by the business, the amount of electricity consumed by Air conditioning systems, electricity consumption profile and air conditioning consumption profile (daily, weekly, monthly, annual), ability to sell electricity and / or cold water for air conditioning to neighboring businesses, etc. In any case, in the design of co-generation facilities, the size of the facility is determined by the residual heat consumption required to produce a suitable amount of cold water for air conditioning, or steam and / or hot water for technological processes, or both cold water and steam and / or hot water in the three-system. Generation.
Example of an approach in choosing the type of facility - Master Plan 3700.
Examples of industrial plants in which it makes economic sense to implement co-generation systems.
Examples of applications of co-generation facilities at sites and civic institutions.

He holds a bachelor's degree in computer science and general philosophy from Bar Ilan University. He is currently the ExpertPower Product Manager at Cytech. At the beginning of his career, he was a member of the IAI team that won the Israel Security Award for developing an electronic intelligence system. Formerly VP of Development at PeriGen, a company that analyzes fetal monitor signal for early detection of fetal distress. Developer in the field of Deep Learning-based diagnostics. Has extensive experience in characterizing and implementing decision support systems, as well as development management in Agile methodology.
Private electricity producers are required to meet the standards, enable the management of the system by the electricity company and on the other hand provide a solution and service to customers while maximizing efficiency.
The lecture will review the roles of the various players and the systems that take part in the core processes carried out as part of the day-to-day management of a private power plant, and how an appropriate software solution has evolved and developed in light of the accumulated experience of working with different clients over the years.
Among other things, the tools for creating and approving a consumption plan, production plan and receiving a daily loading plan in front of the IEC system management unit, forecasting consumption based on weather forecast, BI capabilities for monitoring and analyzing customer consumption over time and monitoring retrospective accuracy will be described.
In addition, there will be an overview of the production of detailed electricity bills for customers, billing control with the electricity company, work processes with the electricity supplier / marketer, monitoring of equivalent availability, steam production plan, gas orders and alert capabilities and production of reports.
Another issue is interfaces and communication between the systems, such as the reception of share data from the mass department, private superiors that provide current data, interfacing with YMM and interfacing with the station owner's financial systems.
We will conclude the lecture by discussing the following challenges in light of the expected developments in regulation and the market in general.
