A webinar titled \” Fire Your Boilers\” was conducted by Aspiration Energy.   Conventional heating systems involve the use of boilers as primary sources of heat using fossil fuels such as Diesel, Electricity, or LPG.   They are not however, used as efficiently as possible – often used at low loads and efficiencies.   This is because the energy utilised at the point of utilisation is low and boiler losses also constitute a large portion of the problems. For example, boilers are used in initial loading conditions at high efficiencies of upto 70 percent, but lose the efficiency at constant low load conditions.   One way of increasing the utilisation efficiency is to use accumulators that store the water/steam produced at high load, high efficiency conditions.   Reducing the boiler losses such as standby and flue gas losses is an another method.   Monitoring the energy consumption using thermal monitoring systems to study the efficiency is also recommended.   However the most sustainable and at the same time, economical solution is to replace them with heat pumps as primary sources of heat.   Heat pumps are highly efficient machines that use the ambient heat in the surroundings to heat the process. They can produce temperatures that a conventional low temperature boiler can produce.   This webinar deals with the issues that are part of the firing a boiler and the advantages of using the heat pumps as full replacement or solar thermal as partial replacement.   The presentation can be viewed below.

Webinar on the title – \”Heat Pumps – An introduction\” was conducted by Aspiration Energy in September 2017.   Heat Pumps are devices that transfer heat from a colder area to the hotter area by using mechanical energy.   Working of heat pumps is based on taking heat from the ambient air to deliver it for the processes which requires it, by exploiting the low boiling points refrigerants.   It consists of an evaporator, compressor, condenser, expansion valve – the same as in a refrigerator. How is this a sustainable device? We shall look into this.   It has to do with its efficiency or coefficient of performance – which is, counter-intuitively more than one. Heat pumps as described before use electrical energy to pump heat from the ambient air to  the process, electrical energy being the input and heat as output. In the case of heat pumps the energy delivered as heat is at least 2 times more than the electrical energy, the remainder of the heat being transferred from the ambient air.   In mechanical terms, it means that every unit of electrical energy used produces 2 units (kW) of  heat energy.   Air conditioners do the same process. Here\’s how: Power consumption        = 2 Units (1 Unit=1 kWh) 1 Ton of refrigerants        = 3512 W A conventional AC delivers an output of 1.5 tonne. Energy Output                  = 3512 x 1.5 TR = 5268 W Therefore the efficiency = Output/Input = 5.268/2 = 2.634   This is also how heat pumps work with the only difference being that heat is delivered and not absorbed as in the case of ACs.   This makes heat pumps a clean and sustainable source of heat and they are being used extensively in industries as alternative replacements for boilers.   The full webinar talks about this and more for educational purposes.     The presentation can be viewed below.   Heat pumps – An Introduction from aeplindia   The video recording of the presentation is below.
