Explained: On-road costs | AA New Zealand

Make sure you ask the dealer for a breakdown of the ORC - if the dealer is unable to provide this, you may be paying for unnecessary add-ons. We decided to contact several used car dealers across New Zealand and enquire about their on-road costs and what was included. To compare these costs, we looked at the popular Toyota Aqua Hybrid which

4 FAQs about [New Zealand orc power systems]

What is an Orc Rankine cycle?

ORC systems are typically used for four major applications: waste heat recovery, geothermal power plants, biomass combustion plants and solar thermal plants. The primary difference between an ORC and a traditional steam Rankine cycle is the use of an organic working fluid, such as ammonia, pentane or a halocarbon.

What is a 1 kW Orc?

The unit is a 1 kW ORC consisting of four key components: evaporator, expander, condenser and pump. Selection of the working fluid was found to be a constraining factor in the design. A refrigerant mix known as HFC-M1 was selected due to its desirable performance, high safety and ease of availability in New Zealand.

What is the thermal efficiency of an Orc system?

The thermal efficiency estimated for this design is 5.7%. The efficiency of an ORC system is typically very low due to the low resource temperatures which they utilize. The Carnot efficiency of a cycle is the theoretical maximum efficiency for a thermodynamic cycle.

What is the most expensive component in an Orc system?

The system turbine is typically the most costly component in an ORC system as it needs to be precision engineered. The turbine is the most vital element in an ORC system as it allows fluid energy to be extracted via an expansion process.
