Ensave Air Compressor saving principle and structure
Saving Principle
To understand the saving principle of our Ensave system, it will be appropriate if we take an example of one of our customer air compressor’s data. The company's compressor pressure set to: maximum pressure of 0.8Mpa and the lower pressure of 0.53Mpa. For a unit load, the loading time and the unloading time are about 2 / 1. Part of the air compressor’s time works in the unloaded state with low efficiency, and power wastage. At this point the so-called unloading where the compressor is not acting, and in the empty state, and then this part of the energy is wasted. Another reason for the lower limit set at 0.53Mpa, that is the minimum 0.53Mpa gas can be used in production, and the pressure increases from 0.53Mpa to 0.8Mpa (loading) will result in a large wastage of electricity. With our Ensave air compressor dedicated Saver which uses a specially designed pressure control system which sets a reasonable supplies pressure, such as for this case 0.55Mpa. When the system pressure is higher than this pressure, Ensave Saver reduces the compressor’s speed, and then doubled down the compressor power consumption.
When the gas consumption increases, Ensave Saver increases the compressor speed so causing rapid increases in pressure in a short-term. And so achieve two objectives: energy-saving and constant pressure air supply. Meanwhile, the compressor motor starting mode becomes soft starter, which in turn can protect the compressor and the motor, and greatly extended their service life.
At present most of the usage (volume) of the air compressor systems for all production needs is set at the standard in the upper and lower limits. When start running, if the size of the load condition makes air compressors produce more unloading time, the greater the loading and unloading proportion, the more the energy is being wasted. And result in a significant waste of energy.

ESI-B500Y Series Energy Saving System
Product Introduction:
Ensave B500Y Series Smart Centralized Air-condition system is safe and reliable. It not only has overload protection, failure bypass protection function, but also stabilizes the voltage, suppress over-voltage fluctuation amplitude, reduce network losses, improve power factor, and improved power efficiency, which brought great convenience to the user.
Principle of Ensave Energy saving system for Centralized Air Condition
The operating principle of the water pump and fan of fluid transmission equipment is that, the flow (air quantity) of the water pump and fan is in direct proportion to their rotation speed. The pressure (head) of the water pump and fan is in direct proportion to the square of their rotation speed. The shaft power of the water pump and fan is equal to the product of the flow and pressure, so the shaft power of the water pump and fan is in direct proportion to the cube of their rotation speed (that is, in direct proportion to the cube of the power frequency). Based on the above principle, if the rotation speed of the water pump and fan is reduced, the power of the water pump and fan can be reduced to a greater extent.
For example, if the power frequency is reduced from 50Hz to 45Hz, P45/P50=(45/50)3=0.729. That is, P45=0.729P50 (P stands for the shaft power of the motor); if the power frequency is reduced from 50Hz to 40Hz, P40/P50=(40/50)3=0.512, that is, P40=0.512P50 (P stands for the shaft power of the motor).
As shown above, if the Ensave B500Y is used for flow (air quantity) control, a large volume of electric energy can be saved. During the design of a central air conditioning system, consideration is given to the maximum on-site cooling capacity requirement. Its chilled water pump and cooling water pump are considered according to the maximum operating conditions of a single piece of equipment. In actual application, the chilled water pump and cooling water pump operate in a non-full load state at over 90% of the time. The regulation with valves and automatic valves not only increases the flow control loss of the system, but also causes the operation of the entire air conditioning system at fluctuation state due to staged regulation.
However, if the Ensave B500Y is added to the cooling water pump and chilled water pump, the problem can be solved permanently, and furthermore, automatic control can be implemented, and investment can be returned by the use of the Ensave B500Y for energy saving. Furthermore, the soft start function and smooth regulation feature of the Ensave B500Y can stabilizes the regulation and operating state of the system, and prolong the service life of the unit and network management system. Therefore, the air conditioning system whose water flow varies with the heat load can perform more efficiently in terms of energy saving.
The use of Ensave B500Y to regulate the rotation speed of pumps can conveniently regulate the water flow. Through PID regulation, the feedback signal that varies with the load and the Ensave B500Y form a closed loop control system, so that the rotation speed of the pump can vary with the load to save energy. Normally, the energy-saving rate is over 15%. The energy-saving rate in the building is closely related to the usage by the user. Normally, the energy-saving rate is higher in the cooling environment (over 20%), while the energy-saving space is limited in the hotter environment due to the greater demand of users for electric power (normally 12%).
Conservation and energy efficiency is the new mantra, whether it is the individual consumers or business or government corporations. From a longer-term perspective, as part of coping with high and rising energy prices, it is time for us to converse energy with the help of Ensave ESII Energy Saving System, an eco-friendly product.

ESHydro - ECP600S Constant Pressure System
The ECP600S Constant Pressure System is the perfect pump to supply constant pressure for house, high rise building, industry or commercial application. It comes along with a pressure tank, pressure gauge and pressure transducer. The pump will speed up or slow down automatically in response to an increase or decrease in water demand, and it will really maintain a true constant pressure so there will be no more annoying pressure fluctuations when the second shower was turned on.
OPERATION
When the system is installed and commissioned, the required operating pressure will be set. The pressure is continually monitored during operation via the pressure transducer located on the discharge manifold. As the flow demand increases (more outlets turned on), the pressure transducer senses a slight drop in pressure and increases the speed of the pump (water flow rate increases) so that it maintains the pressure at the higher flow rate. So, the system checks the actual operation data against the allowable operation range and sets necessary actions to avoid operation below a certain flow rate. This is done by reducing the speed or shutting down if operation within the allowable range cannot be reached.
After an interruption to the water supply, this system will start automatically. A rotating motor will be caught by the E600 controller and the torque will be established smoothly. And it results in a higher reliability and a longer maintenance interval for the motor.
BENEFITS
Ensave ECP600S offers several benefits, some of which are relatively easy to quantify, and others which are less tangible.
Efficient Energy Saving. It can superimpose the pressure of water distribution system with a saving of at least 20% than that of traditional quadratic pressurizes water supply equipment.
Improved Process Control. By matching pump output flow or pressure directly to the process requirements several variations can be corrected more rapidly, which improves process performance. There are fewer livelihoods of flow or pressure surges when the control device provides rate of change, which are virtually infinitely variable.
Improved System Reliability. The reduction in speed of the pump has major benefits in reducing pump wear particularly in bearings and seals.
COVERAGE

ESHydro - ECW Chilled Water Storage System
Cooling is a main concern of commercial building owners. Many building are populated with people, heat-emitting office and production equipment, and ample lighting – all generating so much heat that cooling is required during most of the working hours all year. Most of these hours occur during the peak hours defined by the electric rate structure. Cool storage can shift all or most of this use to lower-cost off-peak hours resulting in lower operating cost without sacrificing occupant comfort, and can contribute to improved utility load factors. Typically, this is done by storing chilling water in a tank during the night, and drawing from it during the day to provide space cooling.
Most power generating facilities reach their peak capacity during the middle of the day. In order to meet the demand of their customers, they must size their production facilities for this peak production. To compensate for the cost of over-sizing their equipment, they often bill demand charges for the largest users.
Thermally stratified chilled water storage systems reliably maintain thermal separation by taking advantage of gravity to maintain the heavier chilled water separate from the lighter return water. So, the water will stratify into horizontal layers according to temperature, forming a natural barrier between warm and cold water in the tank (Refer to picture above). This region is called the thermocline, and acts like a physical boundary between supply and return water. The thermocline is shifted upward as the tank is charged, and downward as the tank is discharged.
From the utility perspective, the use of cool storage by commercial customers makes more efficient use of existing generating capacity and can reduce the need for new capacity.
The advantages to the customer can include first cost benefits, a lowered bill and increased operational flexibility. The use of cool storage decreases electric costs by reducing the building’s peak electricity demand. As in most countries there is a substantial rate different between day time (on-peak) and night time (off-peak).
Chilled water storage can offer significant reductions in chiller energy consumption because it allows the chiller to operate at efficient capacity levels and, generally, at reduced condenser temperatures.
This type of system is suitably for use in Airport, Hotel, Shopping mall, Hospital, Service apartment, and those places which has a high demand for air conditioning.
