How a Sanyo Gas Engine VRF Air Conditioner Works

The only difference between a conventional Sanyo Electric VRF and a Sanyo Gas Engine GHP air is the outdoor unit. The compressors are belt driven by a Nissan car engine running on main gas or LPG. Everything else is the same – indoor units, pipework and controllers. Instead of arranging a mains electrical supply to the outdoor unit, the installer needs to arrange a mains or bottled gas supply at standard mains pressure for each outdoor unit – about 21mBar. A 20HP/56kW Gas engine consumes mains gas at approximately 4cubic Metres per hour.

Features & Benefits

 - Preserve your client's electrical supply

 - Recover waste engine heat for hot water supply-increases COP up to 7

 - Reduced CO2 emissions (and increase BREEAM score)

 - Continuous heating (no defrost, even at low ambient) means a Gas Engine can be used as sole source of heating

Commissioning

All quotations from ESS for GHP product include on-site commissioning assistance. The engines themselves will be commissioned by Sanyo & ESS. You engineers will need to be in attendance.

Service and Maintenance

The engines have a 10,000 hour service interval. This is about 3 years for a normal office application, but will come much sooner if the system runs 24/7. We can quote for the supply of the service kit for each unit, comprising oil, belt and spark plugs and also to provide an engineer to carry out the servicing or to train your maintenance engineers on site. Each outdoor unit has a running hours clock so that the service can be anticipated. There is a warning at 9,000 hours - once 10,500 hours has elapsed without a service, the system will shut down. Prices do not include VAT.
