Whats your entering and leaving water temps
air in out etc etc etc etc etc etc
I have this climate master water source hp freezing up on me, Model # GLV080 The suction is goes to to 25 psig, tempareture goes below 30 degrees and shuts off on code 4 I think the valve is stuck I tried to add freon to it did change anything, I don't think is low on freon, this unit is only a year old and I don't think the loop is dirty because the tepm drop was less than 10 degrees. I don't have alot experiance on these units, I'll appericiate your help.
Whats your entering and leaving water temps
air in out etc etc etc etc etc etc
50 degrees going in 42 degrees going out I didn't check air temperature but it was around 58 degrees in the house, and when it was running it was heating for few minutes before it would go out on the safety.
A guy will need head pressures, might be cooling off too fast and forming a layer of ice on coil and tripping safety.
Do it right the first time.
The head pressure was 210 and sucton was around 30.
Is this a geothermal system or is it tied into city water . Either one can have its own issues related to water flow
It's in a 13th floor in a high rise, water tower in Dallas TX, it's not that cold.
Metering Device???
Looks like you don't have enough water through it. Inlet is 58 degrees with outlet goes down to 30 degrees. Then it goes to lock out. That's is 30 degrees drop.
You may have trash in the pipe.
check the strainer if it has one, difinitely a wtarflow issue
There is no strainer, and I want to know how you clean these loops, and how do u check for water pressure drop or temperature, this is a 1.5 or 2 inch pipe my tepmeratre clamp won't clamp on it, I know y entering water temperature was a50 degrees becuase I could check it during off cycle in the smaller pipe inside the unit but I couldn't check it during runing time because it was close to freon line, and I couldn't check it very properly with my probe temp sensor.
since you said this was a tower, usually there is a small boiler either on the roof with the tower or in the basement. this fires to keep the loop at about 70 degrees. 58 degrees is too cold for a non geothermal water source heat pump. any hp's with lower water flow and low temps will freeze up. water temp or flow needs to go up.
He said entering water temp was 50 and leaving water temp was 42 deg. This is fine, normal water delta T in heat should be 4 to 8 deg. and in cooling 9 to 12 deg.
I agree that the loop temp needs to come up to at least 65 deg and then you should recheck the unit. There should be a control system that will bring the boilers on to suppliment heat to the loop. Check with the maint guy at the building and ask him why the loop is so cold.
As far as checking pressure drop on the unit it should have a braided hose kit with a flow regulating device on the return hose kit. There should be some petes plugs on both hose kits to check temp and pressure.
As far as flushing, you can pull the return hose lose and backflush into a bucket. But again, if you only have an 8 degree drop flow is not your problem.
This is not in the Ritz Carlton or Azure building is it?

I asked the maintenace guy he wasn't aware of any boilers to heat the water. There was a developer in charge of this building and he didn't put any strainer on any of these units, as far as I know none of the other units were acting up what, Is strainer a mandatory, and I want to know what instrument to have to check water pressure and temp.
we had the same problem on two units less than a year old.both were txv powerheads.I hope the loop piping is insulated at the temps its running!
raise incoming water temp
Imagination is more important than knowledge. Knowledge is limited. Imagination encircles the world... AE
All data posted lead to low incoming water temp. There should be a boiler on the loop to maintain at least 65-68 f going into the H.P. If you are running lower water temps the return line will start to sweat like crasy. Also each H.p should have a strainer & some kind of a balancing valve ( Griswold, B & G circut setter ) with pilot ports to measure flow rate.
I would first investigate as to why you are not getting the correct water temps. Then proceed to the next.
If this is the building I am thinking of there is no boiler. By design the loop was intended to be supplimented with heat by the condenser water from the chillers that run 24/7 via some flat plates.
But the OP did not answer my question so it may be a different building.
