Energy Saving opportunities in Normal Operation
The use of the Thermal Inertia of the Building in the air conditioning for a Start, turn off After the whole building is cold, it will take a few hours to get back to a normal temperature. This building thermal inertia can be used to reduce climate equipment of working time by turning off the air-conditioning system, half-hour or hour before closing.
Put HVAC Window Air Conditoners and Split system Timer or Accommodation Sensing Control
Window air conditioners and Split air conditioners are installed for office cabins can work without the need for a long time without cabins occupied. Using timers or infrared sensors can help swtich these machines automatically.
Lock fan coils in Hotels with door Lock or the main Switch In hotels, unnecessary fan coils can be prevented by providing lock with locking system or switching control at the front Desk. Fan fan-coil should get off or go to the low speed mode and cooling water consumption should be cut off by a solenoid valve. This can reduce the air conditioning load in business hotels in the daytime, when the rooms are not occupied.
Increase The Level Of Ambient Air.
In systems with possibility of installation, using the fresh air, make the most of fresh air, when environmental conditions are favorable.
To maintain the Correct Concentration of antifreeze
In systems operating under 5C, maintain brine or glycol concentration at the appropriate levels, it has a significant influence on heat transfer and/or pumping energy.
Installation Of Control Systems Hmm Coordinate Multiple Chillers.
The study, part-load characteristics and Cycling costs to determine the most efficient mode for operating multiple chillers.
Launch of refrigerating machines with low operating costs serve as the base load. Links Chiller control building Automation System for maximum savings.
Resolution Lower Condenser Pressures under Favorable Environmental Conditions environmental conditions, reduce the cooling air the temperature of the cooling water, which will reduce the condensing temperatures and pressures, thus, reducing the power of the compressor. Control systems can allow the machine to run at a lower pressure in the condenser.
Optimize Water/Coolant Flow Of Air
Optimization of the water flow condenser and chilled water/brine flow to maintain the design temperature difference across the coolers and condensers. air flow rate. For the normal process cooling and air conditioning chilled water flow rate, as a rule, at the level of about 2.4 gpm/TR cooling load and cooling water consumption is about 3 gpm/TR cooling load. For a comfortable air-conditioning of the air flow rate is usually about 400 cubic feet/TR. In situations when the threads above, speed reduction should be considered. Electronic variable speed drives stream can be modified to fit workload performance by maintaining a constant temperature drop or pick-up the evaporator and condenser at all times...
