What is Variable Refrigerant Flow (VRF)?
VRF is a HVAC technology that uses refrigerant as the cooling and heating medium. The refrigerant is conditioned by an outdoor condensing unit and circulated within the building to multiple indoor fan coil units where heat or cool air is distributed. Unlike traditional HVAC, VRF systems can be configured in ducted or non-ducted applications, so indoor fan coil units may be installed in any space. Another VRF advantage is the ability for each zone to be controlled by its own thermostat. This enables different zones to have varying temperatures at the same time, and for heating and cooling to occur in different zones simultaneously.
What does GHP stand for?
Gas Heat Pump
How do I know if I have enough gas to the site?
Your gas network utility provider is able to provide you with this information or feel free to call LSM Energy Solutions for assistants.
Can each room/building set its own desired temperatures?
Yes, each room can have a wall controller that can be used to select the desired temperature. Building control modules allow you to set the temperature for the entire building based on occupancy or the buildings desired conditions and more. Several options are available from single room, suite or office controls, to automated building controls specifically designed for multi-family/purpose buildings, to commercial controls designed to lower emissions while reducing energy consumption.
How does the Yanmar Gas Powered Air Conditioning system work?
These are refrigerated air conditioning systems. The gas is used to power an engine that drives the air conditioning compressor. In a traditional electric system, the compressor is driven by an electric motor.
How often does the engine need to be serviced?
On average, every 10,000 engine hours or 5 years subject to model and operating conditions. The system will warn you before a service is due. The service is similar to servicing a car engine – change the oil, oil filter, air cleaner element, spark plugs etc.
How much will it save in energy costs?
This will depend on the local natural gas and electricity utility providers in your area, but many commercial customers in Canada will see the energy cost of the outdoor unit reduced by 30% to 70%. Call LSM for an energy audit and see for yourself.
Will the Yanmar gas powered air conditioner cost more to install?
Not necessarily, for example if the building only has single-phase power, it would typically cost less as compared to an electric 3-phase appliance, as it requires no utility upgrades. The installation cost as compared to an electric appliance in new constructions is very similar, other than powering the unit (gas verses electricity), the same refrigeration line-sets (pipe length & sizes) are required for the distribution system as well as ducted or non-ducted units. Always call your local LSM Certified Yanmar Installer and obtain a quotation for product and installation costs before proceeding as conditions and regulations change from community to community.
What gas pressure is required to the unit?
Does using an engine make these systems noisy?
No, Yanmar VRF Gas heat pumps are reliably quiet, easily compared to any kitchen appliance such as, an energy efficient dishwasher. They are designed to operate at very low noise levels and can be installed next to windows or balconies. Most models are as quiet or quieter than an equivalent electric unit.
Is it safe to use gas for air conditioning?
Yes, it is very safe. All Yanmar products are CSA approved. Installation of any of Yanmar’s gas energy solutions (GHP) are very similar to installing a boiler. The gas is consumed outside the building. All gas installations are completed in accordance with the relevant Canadian and Provincial/Territory safety requirements.
Will using gas affect the indoor air quality of the building?
No, the system only uses gas to drive an engine in the outdoor unit. The indoor units that provide the warm or cool air to the rooms/building are powered by electricity in the normal way. This means the indoor air quality is the same for the gas powered air conditioning system as an equivalent electric reverse cycle air conditioning system.
