Innovative Module Generates Hot Water from Toshiba VRF Systems

LEATHERHEAD, UK, 26 June 2019 – Toshiba’s Super Heat Recovery Multi (SHRM-e) variable refrigerant flow (VRF) air conditioning system can now be used to produce hot water up to 82 degrees Celsius by adding an innovative hot water module. Toshiba Carrier UK Ltd (TCUK) is a joint venture between Toshiba Carrier Corporation and Carrier in the United Kingdom, and is part of Carrier, a leading global provider of innovative heating, ventilating and air conditioning (HVAC), refrigeration, fire, security and building automation technologies.

The unit transforms Toshiba’s award-winning three-pipe VRF air conditioning system into a highly efficient hot water generator that is ideal for use in hotels, gyms, restaurants, shops and offices. With a wide operating range from minus 25 to 40 degrees Celsius, it can produce hot water year-round without impacting normal cooling and heating operation.

It uses a cascade heat exchanger to harness the output from SHRMe’s high performance heat pump, adding a second stage of compression to upgrade the energy to produce high temperature hot water via a refrigerant-to-water heat exchanger.

Neil Hitching, sales director of Toshiba, said, “By utilising heat that would otherwise be wasted, the SHRMe system saves energy, increases efficiency, and reduces the level of heat exhaust. Adding the hot water module is a highly effective way of producing low-cost hot water for use in many different applications overcoming the need for a separate boiler or electric water heater completely, or providing additional capacity to meet peak demand, for example in hotels.”

The energy costs for hot water production compared to a conventional electric immersion system are significantly cheaper. For example, heating 3000L of water from 15 degrees Celsius to 65 degrees Celsius using an electric system costs £23.00, whereas using the hot water module costs just £6.62, less than a third of the cost.

The high temperature hot water module is available in 5HP configuration, which is capable of providing 14kW of heating to generate hot water up to 82 degrees Celsius. Up to two modules can be combined per SHRMe system.
