Power limiter connection?

[s0lid]

Is is possible to make an power limiter circuit for an SS?
If i'm planning to use an SS 24/7, but i'd like to cut the electrical bill somehow. And i have somekinda plan:

Is it possible to cut the compressors power to 70-80% after the pulldown and system start up?

For exsample: Pulldown -> 100%, System boot -> 100%, Boinc gets on and load gets to max -> 100%, Temps get steady and compressors power drops to 80%.

Hope u get my point :D
Halp plz :)

As evap temp drops aka idle and such, power draw drops already.
Past that, no, and I suggest picking up a few good books on electronics and electricity in general to see why ;)

i would agree with NoL, get an electronics book. I suppose you could make a setup to where your compressor is in parallel with a Zenor Diode so electricity conducts as soon the the AC gets above a cirtain point. However, this would work ur capacitor a bit more because the AC wave isnt hitting the compressor coil as constant.

I'm studying electronics and electricity second year now :D
I got the point now, it's not possible to controll the power usage of compressor, kthxbai :P

large Wattage small resistor in series or zenor diode in parallel with a larger cap....

do you have an instructor to contact? im in industrial electronics as well. just working with PLCs atm

Ye i know some friends who are hi-skilled electronic engineers and so on :D

And btw Zenor diode -> Zener diode ;)

What would happen if adjusting the compressor frequency lower?

[Spoobs]

compressors in works with the capacitor. it would change the total impedance of the circuit and it may put to much voltage on the compressor coils and you would need to change the capacitor value.

just get a smaller compressor then,frequency drives are expensive.If you change the frequency you must change the voltage also.

A compressors cooling capacity and Hp are rated at a specific load at a point in time. Usually rated at the maximum @ a given temperature.This can be varied by the pressure ratio,refrigerant, metering device and condensor....ect,ect.

You can also ensure that your system runs at maximum efficency by using an appropriately oversized condensor.

The short answer is no. It would cost you more than you'd save.

Well the nature of thermodynamics is the cooler the motor runs,the less current it draws.
