Can you use existing PVC conduit run from basement to 8th floor for 120v circuits for chillers?

The simple answer to your question is yes.
But there are limits to how many wires can be in any conduit, and the current carrying capacity of the conductors can be affected by distance, ambient temperature, and how many conductors are contained in the same conduit.
Other things to consider are, Can you physically fit the wires in there? Would it be easier to run a new conduit? Do you have the manpower necessary to get the work done?

Is conduit required for basement electrical outlets?
Conduit is not required for residential electrical IF THE WIRING IS BEHIND THE WALL. If it's exposed wiring, you'll need to use conduit.
Can you run 110 and 220 volt circuits in the same conduit?
Yes, 120 and 240 volts can be run in the same conduit.
Is a separate ground wire required for each circuit in a conduit?
Not normally. An elaboration of what circuits are in the conduit and what type of conduit it is would be useful, though, and necessary to give a definitive answer.
What kinds of accessories are used in full conduit wiring?
If the conduit has reached its limit as to how many wires can be in it, there is only one course of action and that it to install another conduit parallel to the existing one. The electrical code book only allows a certain cross sectional filling of any conduit size. The rule is based on the dissipation of heat from the conductors in the circuits through the conduit walls. Once the wire fill has reached that figure no more wires should be pulled in because of insulation heating. Over time the heating of the insulation could lead to insulation breakdown and then short circuiting of the existing conductors that are in the same conduit.
To rewire a 2 bedroom property that was built in 1956 Can we use the old conduit or Do we need to replace it Currently earth is attached to the conduit itself Any special cables we can use?
If the existing conduit has not been intentionally or accidentally interrupted it is still an adequate ground. If you are in doubt about this or if a test proves that it is not grounded, new conductors including a new ground wire can be pulled inside the conduit. If the existing conduit is flexible conduit and it has "jake" type twist connectors, rewiring with a ground is advisable as those type of connectors do not maintain a good ground connection.
Can branch circuits from a panel be pulled in the same conduit if not exeeding the conduit fill requirements?
Yes. The thing that has to be closely watched is the load on the conductors. The conductors will have to be de-rated as the code only gives amperage rating for three conductors in a raceway. So watch the connected amperage to each load and fill the conduit accordingly. This supersedes the conduit fill requirements rule.
What kind of DIY projects can a conduit elbow be used for?
Conduit comes in many styles and is used to run electrical wiring in exposed locations in and around your home. It may be a basement, garage, barn, laundry areas, and also exposed areas.
Can you run two 2 pole single phase circuits in the same conduit?
Yes, this only adds up to four wires. The wire sizing is dependant on the amperage of the two single phase loads. Remember to calculate the conduit fill of the four wires to make sure that you have the correct size conduit for the installation.
What is done in conduit diversion?
Conduit diversion involves redirecting water flow from a natural stream or river into a man-made channel or conduit. This can be done for various purposes such as irrigation, hydroelectric power generation, or water supply for cities and towns. It is a common practice in water management to efficiently utilize the available water resources.
What is conduit wiring?
Conduit wiring is synonymous to wires in a pipe.
Electrical metallic tubing would be used in an electrical installation because it?
The type of conduit system is governed by two factors. One the code book states what type of system can be places in what specific locations. The second factor is what the electrical engineer specifies that what he wants the conduit system to be on his project. EMT is used in the majority of jobs for industrial and commercial projects. As a conduit system it is easy to install and more circuits can be added to the system very easily abiding by the code book rules for conduit fill.
Which conduit is best - PVC or MS conduit?
For underground conduit runs, PVC is by far the better of the two conduit systems.
