To convert a plus chiller to a minus chiller package, the refrigeration system needs to be modified to accommodate the change in temperature requirements.

• Modify the refrigeration system to allow for lower temperatures

• Adjust the settings and controls to operate at negative temperatures

• Install additional insulation to maintain lower temperatures

• Replace any components that are not rated for sub-zero temperatures

Inverter changes speed based on load, while fixed speed operates at a constant speed.

• Inverter adjusts motor speed to match the required load, saving energy and reducing wear and tear.

• Fixed speed motors operate at a constant speed regardless of the load, leading to higher energy consumption.

• Inverter technology is commonly used in air conditioners and refrigerators for energy efficiency.

• Fixed speed motors are often found...read more

Pump HP is calculated using the formula: HP = (Q x H) / (3960 x Efficiency)

• HP = Horsepower of the pump

• Q = Flow rate of the pump in gallons per minute (GPM)

• H = Total head in feet

• Efficiency = Efficiency of the pump as a decimal

Suction head is the vertical distance between the pump impeller and the surface of the liquid being pumped.

• Suction head is important in determining the efficiency of a pump.

• It is crucial for ensuring that the pump does not cavitate, which can damage the pump.

• Examples of suction head include static suction head and dynamic suction head.

Chiller selection is based on various parameters such as cooling capacity, efficiency, size, noise level, and cost.

• Cooling capacity: Determine the required cooling capacity based on the size of the space and heat load.

• Efficiency: Look for energy-efficient models to reduce operating costs.

• Size: Consider the physical dimensions of the chiller to ensure it fits in the designated space.

• Noise level: Choose a chiller with lo...read more

The inlet and outlet temperatures for both the evaporator and condenser depend on the ambient conditions prescribed by ISHRAE.

• Inlet and outlet temperatures for the evaporator and condenser will vary based on the ambient conditions specified by ISHRAE standards.

• For air-cooled systems, the inlet temperature for the evaporator is typically higher than the outlet temperature, while the opposite is true for the condenser.

• IS...read more

Designing ODU VRF with AHU involves selecting compatible units, determining capacity requirements, and ensuring proper installation.

• Select compatible ODU VRF and AHU units based on capacity and efficiency requirements

• Calculate the total cooling and heating load of the space to determine the capacity needed

• Design the refrigerant piping and electrical connections between the ODU VRF and AHU

• Ensure proper ventilation and a...read more

Refnets are calculated based on the number of referrals made by an individual.

• Refnets are typically calculated by counting the number of referrals made by an individual.

• The formula for calculating refnets may vary depending on the specific program or system being used.

• Refnets can be used to track the effectiveness of referral programs and the performance of individuals in generating referrals.

PIBCV valves are typically installed on the supply side of the chilled water system.

• PIBCV valves are installed on the supply side to control the flow of chilled water into the system.

• They are often located near the chillers or air handling units.

• PIBCV valves help regulate the temperature of the chilled water circulating in the system.

• These valves are crucial for maintaining the efficiency and performance of the chilled

IK/TR stands for Installment Key/Total Receivables and NPLV stands for Net Present Loan Value.

• IK/TR is a financial metric used to calculate the ratio of total installment payments to total receivables.

• NPLV is a financial metric used to determine the net present value of a loan.

• IK/TR is important for assessing the repayment capacity of borrowers, while NPLV helps in evaluating the profitability of loans.

• Example: If a bo...read more

The MaX COP of VRF systems is typically higher than that of chillers.

• VRF systems generally have a higher COP (Coefficient of Performance) compared to chillers.

• VRF systems can achieve COP values of 4 or higher, while chillers typically have COP values around 2 to 3.

• The higher COP of VRF systems makes them more energy efficient and cost-effective in the long run.

Grouting is the process of filling gaps or spaces between tiles or masonry with a cement-based material.

• Grouting helps to create a uniform and stable surface.

• It prevents water from seeping through gaps and causing damage.

• Grouting can be done with different types of materials such as cement, epoxy, or urethane.

• The process involves mixing the grout material with water to form a paste, applying it to the gaps, and then wi...read more
