ECOg - gaz VRF systems

ECO G VRF Systems

ECO G gas VRF is specially designed for buildings where the electricity is restricted or CO2 emissions must be reduced.

 

The new Gas Heat Pump from Panasonic is the ideal solution for projects with electricity supply problems.
  • Operates with LPG or natural gas
  • Suits many applications due to large capacities (from 45 to 142 kW)
  • Operates up to -20°C, without losing any capacity and without defrost cycle
  • Can be connected to all indoor units and controls from Panasonic ECOi lineup
  • Panasonic GHP can also be connected to water heat exchanger for Chilled and hot water production
  • Unique discharge air temperature control to avoid too low supplied air temperatures
  • Discharge air temperature control to provide maximum comfort
  • Panasonic’s New Advanced VRF Software with AutoCAD® compatibility makes design easier than ever

Easy to add additional units in the future
Load can easily be increased in the future by the addition of indoor and outdoor units without having to plumb pipe shafts. When specifying refrigerant pipe work, please choose the size according to the horsepower after the increase of units.
Example of a system. Added outdoor units. (Only for models with the same refrigerant.)
1. If there is a possibility for addition after setting up, please plan it so that the placement of a ball valve (sold separately) on a branch pipe on indoor/outdoor units is possible
2. Main pipe: Maximum gas pipe diameter 38,1 (1 1/2). Maximum fluid pipe diameter 19,05 (3/4)
3. Added indoor units. (Only for models with the same refrigerant.)
 
Maximum possible number of outdoor units to be combined: 2 units. Maximum horsepower of combined outdoor units: 50 HP. Maximum possible number of indoor units to be connected: 48 units(1). Indoor/outdoor units capacity ratio: 50%-130%(2).
1. When 2 outdoor units are connected.
2. Capacity of indoor units connection is: Minimum 50% of the capacity of the smallest outdoor unit within the system. Maximum 130%: total capacity of the system outdoor units. Indoor units are same as multi series for buildings.

Saving Energy
  • Energy savings achieved by the Appropriate Capacity.
  • Equational Program Function.
Energy savings are achieved by the Appropriate Load Divider Function, which enables efficient operation by concentrating the cooling/heating capacity to one outdoor unit and stopping the other. Compared to conventional machines with a similar COP, this function allows energy savings and thus reduces the running costs, especially in part-load seasons like spring and autumn.
1. Up to this time / 2. W-Multi / 3. Load of around 10 HP (8 h operating) / 4. STOP / 5. Total operating hours: 16 hours / 6. Total operating hours: 8 hours
 
Non-stop operation, even during maintenance
  • System will not stop even during maintenance, due to Manual Backup Operating Function.
  • Maintenance is possible during weekdays because it can continue operating during maintenance.
  • Automatic Backup Operating Function enablescontinuous operation.
If one outdoor unit stops the backup function will automatically start on the remaining unit and continue operating. During service intervals, the system being serviced can be isolated by a closing valve in the outdoor unit, enabling continuous operation with the still operative outdoor unit.
1. Up to this time / 2. W-Multi / 3. System stops during maintenance / 4. Continuous operation under the maintenance / 5. Machine in need of maintenance (maintenance during holidays) / 6. Machine in need of maintenance (maintenance during weekdays) / 7. Backup
 
Long lifetime
  • Renewal period prolonged due to rotation function.
Rotation function, which is run from outdoor units with low operating time, will average the operating hours of each outdoor unit. This extends the periods between maintenance or replacement.
Example of the rotation function: 1. Operating hours: 2.100 h (unit 1), 2.050 h (unit 2) / 2. System startup. Only unit 2 is operating / 3. Operating hours: 2.100 h (unit 1), 2.053 h (unit 2). Load increased. Units 1 and 2 are operating / 4. Operating hours: 2.105 h (unit 1), 2.058 h (unit 2). Load reduced. Only unit 2 is operating. / 5. Realization of averaging operating hours
 
Ease of construction
  • By using common header pipe work the installation cost and time is significantly reduced.
By combining all pipes, which were needed for each indoor unit, into a common pipe in each system, the number of pipes are reduced by half* which leads to ease of construction. Furthermore, space of pipes within pipe shafts can be reduced by 2/3.* Combining all pipes, which were needed for each outdoor unit, into a pipe in each system. (Number of pipes is reduced by half). *System with approximately 40 HP (20 HP x 2 units)
Example of a system with approximately 40 HP: 1. Up to this time / 2. W-Multi

With GHP outdoor units:
In heating mode, at very low outdoor temperature -21°C, the available power is maintained. No defrost cycle happens and stable heating comfort is guaranteed.
  • Hot water outlet temperatures from 35°C to 55°C
  • Chilled water outlet temperatures from -15°C to 15°C
  • Outdoor temperature range in cooling mode: -10°C to +43°C
  • Minimum outdoor temperature in heating mode: -21°C
 
ECO G Water Heat Exchanger. Mixed System Application
  • The GHP Multi System can have an indoor unit plus a GHP chiller. When the two systems are operated independently, an outdoor unit with 130% capacity can be connected
1. Outdoor unit / 2. ECO G chiller Water Heat Exchanger / 3. Buffer tank / 4. Control wiring / 5. Refrigerant piping / 6. Water piping / 7. Air handling unit / 8. Duct* / 9. Fan coil unit / 10. Floor heating
 
Note: The mode of running of outdoor unit depends on the Water Heat Exchanger’s mode. The water pump is not included in the Water Heat Exchanger unit. For simultaneous operation, however, the maximum capacity is 130%. Please inquire details of this system design of Panasonic. * Standard DX type indoor unit system.

The Gas Heat Pump (GHP)
Panasonic Gas Heat Pump is the natural choice for commercial projects, especially for those projects where power restrictions apply. As you would expect, all of our Gas Driven VRF systems are designed to give the highest reliability rates. The GHP engine or (internal combustion engine) varies the engine speed to match the building load functions that are comparable with an inverter type electric air conditioner.

2. Fan
3. Accumulator
 
Power supply problems?
If you are short of electrical power, our gas heat pump could be the perfect solution:
  • Runs on natural gas or LPG and just needs single phase supply
  • Enables the building's electrical power supply to be used for other critical electrical demands
  • Reduces capital cost to upgrade power substations to run heating and cooling systems
  • Reduces power loadings within a building especially during peak periods
  • Electricity supply freed up for other uses such as IT servers, commercial refrigeration, manufacturing, lighting etc.
