The Australian summer can be super hot. If you live in Australia, you will want to make sure you can stay cool during the intense heat. I came to realise how important HVAC systems are when I moved into an apartment which didn't have HVAC. It was OK in the winter, but by the summer, it was terrible. I called in an HVAC contractor and asked them to install a new system. It was amazing what a difference it made. The contractor also gave me some advice about how to maintain the system. I hope this blog is useful to you.
Commercial HVAC pumps are critical for the efficient cooling and heating of interior spaces. These components are responsible for forcing the flow of fluids such as the coolant through the system. If the pumping mechanism in your HVAC fails or malfunctions, you will have to deal with indoor climate control problems. If the issues are not resolved, the productivity in your business could decline. Here are practical guidelines for solving common HVAC pump problems.
Replace Seals
HVAC pumps have seals designed and installed to contain fluids. If these components sustain damage, you will have to deal with fluid leakage from the pump. In most cases, pump seals fail because of an unfavourable environment. For example, if the immediate environment has chemicals or is hot, the seal will be damaged and fail. Also, if the seal dries out, it will not perform as expected. If your seals have failed and are already leaking, you should have an HVAC contractor replace the damaged elements. You should also protect the seal by lubricating the element and preventing exposure to unfavourable conditions.
Prevent Cavitation
Pump cavitation occurs in HVAC systems when low pressure bubbles accumulate in the fluids circulating in the appliance. Cavitation can cause a lot of unexpected problems in commercial air conditioners. For instance, the air bubbles in the fluid will cause the accelerated degradation of the impeller. Also, the sears and bearings in the appliance will wear out faster due to the cavitation. This problem can be managed by minimising the flow of air into the HVAC fluids. For example, you can reduce the total number of valves, decrease the fluid temperature and shorten flow pipes.
Check the Pump Shaft
You should check the condition of the shaft if the HVAC pump is not working as expected. The shaft can sustain damage due to an overload or an imbalance during the regular operations. Also, the shaft can deteriorate due to exposure to extreme temperature. If this is the case, you will find that the component has become discoloured. Most of the shaft problems can be resolved through making some adjustments to connected parts. In simple terms, you should reinstall the belts controlling the movement of the pump. You should also check on the condition of the fan and the fan clutch. You should ensure that the fan is mounted on the shaft correctly to minimise strain on the shaft.
If you are uncertain about the problems affecting your commercial air conditioning and heating system, you should consult a contractor for troubleshooting.
