Hamworthy Heating, a trusted British manufacturer and supplier of commercial heating and hot water products is pleased to announce the arrival of two new resources –

‘An Introduction to Heat Pumps’ CIBSE Approved CPD and

‘The Hamworthy Roadmap to Decarbonisation’ White Paper

 

Ideal for specifiers and installers wishing to understand more about heat pumps and the latest industry developments, ‘An Introduction to Heat Pumps’ is the latest CIBSE-accredited Continuous Professional Development (CPD) course from Hamworthy Heating. Covering the main heat pump operating principles such as energy, refrigeration, technology and efficiency, the latest CPD offering from highlights the different types of commercial heat pump equipment available and explores the influencing factors which need to be considered before heat pump selection.

Also focusing on heat pump design principles, ‘An Introduction to Heat Pumps’ looks at the main points to consider when it comes to designing a heat pump system, before concluding with an overview of market drivers and government incentives.

To further support the transition to low carbon heating and hot water, the new ‘Hamworthy Roadmap to Decarbonisation: Planning Your Journey’ White Paper features an in-depth examination of decarbonisation. Looking at the current landscape; the latest White Paper from Hamworthy discusses the challenges of implementing a roadmap to decarbonisation and how heat pumps, such as the Tyneham monobloc air source heat pump, play a pivotal role in this transition.

The Tyneham heat pump is one of the lightest commercial heat pumps on the market. Featuring a coefficient (COP) rating of up to 4.85 to provide efficient, low-carbon heating, the Tyneham includes seven models in the range with six nominal outputs of between 14 to 70kW and can be cascaded to achieve higher outputs in larger installations. Incorporating an inverter controller compressor to accurately match the heat demand, Tyneham heat pumps also use R32 refrigerant to deliver increased efficiencies.

More than just a manufacturer, Hamworthy is a company committed to providing high levels of service and aftercare to its customers. To help customers get the best out of their products and stay up to date with the latest industry developments, Hamworthy Heating – a long-term member of the CIBSE Patrons Programme – offers a range of wide range of CPD seminars and product training courses, delivered by HVAC professional members of the Groupe Atlantic team.

Rinnai’s Pete Seddon details the workings of a commercial heat pump

 

Heat pumps have a leading position in the pecking order of appliances that can work on commercial sites and property and drive towards NetZero and decarbonisation. The ever-growing interest in heat pump technology means an equal amount of curiosity is devoted to how a heat pump works.

What are the main internal mechanisms that enable a smooth operational product life cycle of a heat pump? And what are the inner mechanisms that provide product functionality?


Rinnai have launched a range of blogs and Vlogs entitled

Rinnai Pathways which seek answering questions such as this one

A commercial heat pump operates and uses similar technology in a similar way to an everyday consumer product, a common refrigerator. A “fridge” operates by extracting heat from within the fridge cabinet and exhausts this heat into the room. A heat pump follows a similar process however it is installed outside and extracts heat from the outside air and then transfers the heat generated into a body of water.

A heat pump has four main components within the closed circuit which is also known as the refrigerant circuit.

These components are:

  1. The Compressor.

A compressor is used to move gaseous refrigerant through the refrigeration circuit, and a heat exchanger, which extracts heat from the source. The heat is then passed on to a heat sink through another heat exchanger.

  1. The Condenser.

The condenser is a form of heat exchanger and is used to transfer the heat from the hot compressed gas into the water without coming directly in to contact with each other. As a lot of the heat is removed from the gas it will now change state from a gas to a liquid but will still be high pressure.

  1. The Expansion Device

The expansion device allows the pressure of the refrigerant to be lowered which in turn will allow its state to be changed at lower temperatures which is crucial for the whole process.

  1. The Evaporator.

The evaporator is the component that starts the process all over again and is another form of heat exchanger. By using a fan, it draws air across the Evaporator which allows the refrigerant to change state back into a low-pressure gas ready to go back into the compressor. This then goes back to the compressor to continue to the cycle.

There are of course a lot more components within the heat pump that are integral to its operation and the overall heat pump efficiency such as thermistors to monitor the temperature of the refrigerant and the Control Board to ensure the desired output is achieved.

Commercial heat pumps can transfer heat even in minus temperatures, air source and ground source heat pumps could generate heat as low as -20°C ambient temperature. Conversely, they also create heat at extremely high temperatures. This is achieved because of the low boiling point of the refrigerant gases.

Commercial heat pumps generally use less energy to operate than they output in heat energy, making them extremely efficient – however when the temperature lift for commercial water heating or space heating is substantial (Temperature lift = outdoor air temperature and the temperature heat is delivered at within the building).

The heat pump efficiency i.e., COP or SCOP will reduce, therefore many heat pumps work at their optimum with low temperature heat distribution systems (such as underfloor heating) and why performance reduces dramatically when a heat pump is required to supply heat at high temperature for conventional domestic hot water.

Rinnai’s H3 range of products include domestic and commercial heat pumps that offer immediate property decarbonisation. Rinnai is determined to provide UK customers with cost effective low carbon solutions towards domestic and commercial hot water and building heating provision.
