Variable frequency drive has inherent electronics which could be repaired by only trained personnel. Can we use ordinary single speed motor combined with manually adjustable PIV drive?. Which is economical considering initial,operating & maintenance costs?.

ENERGY MANAGEMENT SYSTEM

An EnMS integrates energy active management into everyday business systems and procedures. The goal is to enable an organizations to better manage their plan do act cycle xpartenergy usage, to achieved operating cost savings, and to continuously improve energy efficiency.

Many governments are either looking into or are actively implementing approaches to encourage industry adoption. One way is to promote compliance with the ISO 50001 energy management standard.

EnMS is becoming an effective way for governments, private and public organizations to reduce energy usage By saving energy or using energy effectively, costs are reduced.
Case studies have shown repeatable business cost improvements from 10% to 70%.

CMMS software centralizes the management, tracking, and optimization of maintenance operations – allowing companies to maximize the availability and use of physical assets like machinery, vehicles, equipment, and infrastructure.

Here’s a brief rundown of some essential CMMS features:

Work order management automates and streamlines the process of creating, assigning, and tracking maintenance tasks

Resource and labor management / scheduling helps your teams effectively allocate human and material resources – leading to greater efficiency and productivity

Asset registry provides a centralized database for all your assets, making it easier to manage and track them across the business

Condition monitoring uses IoT sensors to continuously track the health and status of your assets and equipment, alerting maintenance teams of anomalies as early as possible

Predictive maintenance gathers and analyzes historical and real-time data to forecast when equipment will need servicing and attention – before things fail or break down

Reporting and analytics allows you to stay on top of your KPIs with comprehensive data visualizations and tracking information

Parts and inventory management helps you see and coordinate the availability, location, and status of spare parts, ensuring that the right parts are available when needed

Mobile maintenance functionality allows your technicians to securely use mobile devices to access information and initiate and oversee many maintenance tasks from a remote location

Auditing and compliance tracking helps you confirm that your maintenance activities are documented and compliant with the latest industry and regional regula

Air-Cooled Water Chiller : Animated Schematic to 30 Tons
Air-Cooled Schematic

Compressor ( #1)
The compressor has two functions in the refrigerant cycle. First, it removes the refrigerant v***r from the ev***rator and reduces the pressure in the ev***rator to a point where the desired ev***rating temperature can be maintained. Second, the compressor raises the pressure of the refrigerant v***r to a level high enough so that the temperature is higher than the temperature of the cooling medium available for condensing in the refrigerant v***r.
Air-Cooled Condenser ( #2)
The air-cooled condenser is a heat exchanger where the process heat absorbed by the refrigerant is given off to the air around it. As heat is given off by the high temperature high pressure v***r, its temperature falls until the v***r condenses to a liquid. A centrifugal blower or motor driven fans generate airflow across the condenser.
High Pressure Limit ( #3)
Protects the system against excessive pressure in the refrigerant circuit.
High Pressure Pressure Gauge ( #4)
Provides visual indication of the refrigerant condensing pressure.
Liquid Receiver ( #5)
The receiver is required to hold the system refrigerant charge during service.
Filter Drier ( #6)
The Filter Drier removes moisture, dirt, and other foreign materials from the refrigerant that will harm the system components and reduce efficiency.
Liquid Line Solenoid ( #7)
The Liquid Line Solenoid is an electrically controlled refrigerant flow control valve that closes when the compressor stops. This prevents liquid refrigerant from migrating to the ev***rator and causing liquid slugging when the compressor starts again. Liquid slugging can cause severe damage to the compressor. The valve is opened when the compressor is on.
Refrigerant Sight Glass ( #8)
The Refrigerant Sight Glas allows the operator or serviceman to observe the flow of liquid refrigerant. Adequate refrigerant is determined by a clear liquid flow. Bubbles in the liquid flow indicate a shortage of refrigerant. The moisture indicator provides a warning in the event that moisture enters the system, indicating that service is required. A green indicator signals no moisture content. A yellow indicator signals that the system is contaminated with moisture and requires service.<
Expansion Valve ( #9)
The Expansion Valve meters the flow of liquid refrigerant into the ev***rator at the proper rate to provide cooling of the process water. As more cooling is required, additional refrigerant is metered through the valve into the ev***rator.
Hot Gas Bypass Valve ( #10)
The Hot Gas Bypass Valve (not included with Digital Scroll Compressors) prevents short cycling of the compressor by modulating the compressor capacity. When activated, the valve opens and allows hot refrigerant gas to enter the refrigerant stream entering the ev***rator. This reduces the effective capacity of the system. Units using Digital Scroll Compressors unload internally using energy saving separation of the compressor scroll plates.
Ev***rator ( #11)
The EVAPORATOR is the device in which liquid refrigerant boils, absorbing heat as it ev***rates, cooling the process fluid.
Low Pressure Refrigerant Gauge ( #12)
Provides visual indication of the refrigerant ev***rating pressure.
Low Refrigerant Pressure Limit ( #13)
Protects the system against low pressure in the refrigerant circuit.
Coolant Pump ( #14)
The Coolant Pump circulates chilled fluid through the process loop.
Freezestat Limit ( #15)
The FREEZESTAT aids in protecting the ev***rator from potential freezing. This is an option on most models.
To Process Sensor Probe ( #16)
The To Process Sensor Probe is placed in the coolant flow stream going to the process. Control decisions are made based on the To Process coolant temperature.
Coolant Pressure Gauge ( #17)
Provides visual indication of the coolant pressure supplied to the process.
Water Make-Up Solenoid ( #18)
When activated by the float switch, the WATER MAKE UP SOLENOID will open and introduce supply water to the reservoir. This restores the reservoir to the proper operating level.
Reservoir Level Float Switch ( #19)
The Reservoir Level Float Switch is place at the proper water level in the reservoir. If the water level falls below the proper level, the float switch activates the Water Make-Up Solenoid valve refilling the tank to the proper level.
From Process Sensor Probe ( #20)
The From Process Sensor Probe is placed in the coolant flow stream coming back from the process. Note: this is an option available on LE & HE control instruments only.
Ev***rator Flow Switch ( #21)
The Ev***rator Flow Switch protects the system from low coolant flow conditions that can cause system operating problems and damage. Note: This is an option on most models.
Reservoir ( #22)
The Coolant Reservoir is selected to have adequate volume to support the flow requirements of the chiller. The reservoir is non-pressurized promoting air separation and high process flows.
