A secondary cold water system is a part of a building's cooling infrastructure that distributes chilled water from a central chiller to various cooling units, such as fan coil units or air handling units. This system typically operates at a lower pressure and temperature compared to the primary chilled water system, which generates and circulates the chilled water. The secondary system allows for greater flexibility in controlling temperatures in different areas of a building, enhancing overall energy efficiency and comfort. It often includes components like pumps, piping, and valves to facilitate the movement of chilled water.

In direct system of cold water supply the purpose of the cold feed pipe is to?
In a direct system of cold water supply, the cold feed pipe serves to transport water directly from the mains supply to various outlets, such as taps and appliances, without the need for a storage tank. This pipe ensures a constant and immediate supply of fresh water at mains pressure, allowing for efficient usage in residential or commercial settings. Additionally, it helps maintain the water quality by minimizing stagnation, as the water is continuously supplied from the mains.
What is the purpose of a check valve on recirculating hot water system?
To prevent stratification of the hot water molecules into the cooler water as heat goes to cold
What is a cold tap on a pipe?
A cold tap on a pipe refers to a connection point where a valve or fitting is installed to access the cold water supply within a plumbing system. It allows for the diversion or measurement of cold water flow, often used for maintenance, repairs, or to supply cold water to appliances and fixtures. Cold taps are typically found in residential and commercial plumbing systems for efficiency and convenience.
Where will you find the standard for the soundness testing on a cold and hot water systems?
Your local building department and the Plumbing Code, a normal test for a water system is to prime the system at the pressure it will be running, as long as it's not above 80psi and checking for visible leaks and pressure drop or meter movement.
Why does your combi boiler fire up when the cold water tap is turned on from the mixer tap?
I had a similar problem on a brand new system and researched it. If it cycles when the cold water tap is on, see: http://uk.answers.yahoo.com/question/index?qid=20090809045527AAGRrZj If it cycles when the cold water is off, see: http://www.howtomendit.com/answers.php?id=264190
In area where water supply is poor during periods of peak demand what type of system would usually be specified for a domestic dwelling?
secondary cold water system
What is a chilled water pump?
There are two pumps the primary and the secondary pump. The primary is the chilled water pump which is what pumps cold water throughout the building and the secondary circulates the water.
What is the function of the cold water inlet in a water heater system?
The cold water inlet in a water heater system brings in cold water from the main water supply into the tank, where it is heated up to provide hot water for household use.
What is the function of the hot and cold water valve in a plumbing system?
The hot and cold water valves in a plumbing system control the flow of hot and cold water into the fixtures, allowing users to adjust the temperature of the water coming out of the taps or shower.
Is cold water always on the right?
No, cold water is not always on the right. The location of hot and cold water taps can vary depending on the plumbing system and design of the fixture.
Why is my water cold?
Your water may be cold due to a variety of reasons, such as a malfunctioning water heater, low water pressure, or a problem with the plumbing system. It is recommended to check these potential issues to determine the cause of the cold water.
Why does car engine shut down when its cold?
Don't know how cold your cold is but, it could be water in the fuel system (ice).
Why is my cold water hot?
Your cold water may be hot due to a malfunction in your water heater, where hot water is mixing with the cold water supply. This can happen if the water heater's thermostat is set too high or if there is a cross connection in the plumbing system.
1 describe a direct cold water system and list 2 advantages and 2 disadvantages of this type of system?
A direct cold water system is a plumbing setup where cold water is supplied directly from the mains to the taps and appliances in a building without being stored in a tank. Two advantages of this system are that it provides instant access to cold water without the need for a storage tank, and it can be more energy-efficient as there is no heat loss from a tank. However, two disadvantages are that water pressure can vary depending on demand, and there is a risk of water contamination if there is a backflow issue in the mains supply.
How does a hot and cold mixing valve work to regulate water temperature in a plumbing system?
A hot and cold mixing valve works by combining hot and cold water to achieve a desired temperature. The valve has two inputs for hot and cold water, and a single output that delivers water at the set temperature. By adjusting the proportions of hot and cold water flowing into the valve, the temperature of the output water can be controlled. This helps maintain a consistent and comfortable water temperature in the plumbing system.
How does a hot and cold water mixing valve work to regulate the temperature of water in a plumbing system?
A hot and cold water mixing valve works by combining hot and cold water streams to achieve a desired temperature. The valve has internal components that adjust the flow of each stream to maintain the set temperature. By controlling the ratio of hot and cold water, the valve regulates the overall temperature of the water in the plumbing system.
How do you carry out a soundness on the cold water system?
To carry out a soundness test on a cold water system, you would typically isolate the system, fill it with water, and then pressurize it to a specific level using a pump. The system is then left under pressure for a designated time to observe if there are any leaks. If the pressure remains consistent, it indicates that the system is sound.
