维护Tips for Heating & Cooling Systems

发布者Sam Pelonis|Jun 29, 2015 7:00:00 AM |0 Comments

When customers choose to undertake custom heating or cooling projects, they may not always make as many considerations as industry professionals.

在任何安装开始之前需要解决许多问题,例如与所需系统的位置和特征有关的那些,以及整个项目的成本和能源问题。

There are also many questions to consider when working on the systems once they are set in place; the slightest issue can increase the chances of component degradation or eventual failure. Depending on whether you are working on either a heating or cooling system, there are different questions that are vital to keep in mind.

Q: Is maintenance the same for all kinds of heating systems?

答:由于加热系统略有不同,因此对这些系统的维护也会有所不同。

例如:家庭采暖应用依靠建筑物的热传导,而运输加热应用利用来自车辆本身的能量。一些应用依赖恒温器来调节能量,其他应用是自我限制的。

无论如何,您需要在修理之前考虑申请的特定能源问题和各个组成部分。

问:我的加热系统正在创造异常高的公用事业费用 - 我如何解决这个问题?

A: Higher energy costs can be indicative of poor energy efficiency. The secondary limiting devices that some heating systems depend on can malfunction, leading to an influx of heat energy—which in turn leads to higher energy costs.

要打击此问题,您应该定期检查您的系统是否有任何过热的迹象,并更换任何缺陷的部件。

问:PTC加热器是否需要持续维护?

答:PTC加热器具有比传统的电阻加热器更长的使用寿命。PTC加热限制流过系统的能量,使其不太容易过热或短路。与任何机器一样,PTC加热器可以发生故障 - 如果您注意到任何问题,请检查任何故障电路的加热器。

Q: Is maintenance the same for fans and blowers?

A: Maintenance will be slightly different for fans and blowers since each has unique airflow and pressure characteristics, but generally you should watch for signs of fatigue on belts, bearings, sheaves, and other components. DC fans, DC blowers, micro fans and cross flow fans will each have some differences when it comes to maintenace.

问:为什么系统中有气流问题?

答:您的冷却(和188d金宝搏的网址188体育在线官方加热)系统可以积累碎屑或其他污染物,这会随着时间的推移而导致性能差和损坏的部件。

确保保留这些组件清洁。风扇劣化(引起腐蚀性气体或磨料颗粒)的问题可以避免对系统的周期性检查,以进行任何流量不规则性。

问:什么是需要定期检查的另一个组件?

答:风扇电机的状况对系统的适当操作至关重要。您可以使用诸如振动分析的方法 - 电机速度和刀片通过频率 - 以先发制人地检测电机绕组内的问题。您还可以测量某些电压下的绝缘电阻以测试电机绕组。

Specifications for Heating and Cooling System | Pelonis Tech

发布者Sam Pelonis| 2014年12月22日,7:00:00 |0 Comments

Problem-free operation of heating and cooling systems begins well before consumers even switch on their machines.

在规格阶段,这些系统的设计人员必须考虑多个考虑因素,同时要求自己有关的问题。以下是三个这样的问题,伴随着一些有用的答案。

1.加热/冷却系统是否正确尺寸?188体育在线官方188d金宝搏的网址

188d金宝搏的网址188体育在线官方Cooling_Fan适当的尺寸对于这些系统的理想场所来说至关重要。计算给定设施的加热和冷却要求时,重要的是避免“拇指规则”尺寸的古老188d金宝搏的网址188体育在线官方实践,这使系统大小与设施的总平方英尺相同。

Regarding sizing, be sure to consider these factors: cubic footage to be heated and cooled, insulation and rate of air infiltration, and industry standard protocols for product sizing. These design points will help heating and cooling systems avoid serious issues in the future, including short cycling and excessive equipment wear.

2. With all the different temperature control devices on the market, which is the best for the application?

Delivering optimum heating and cooling is one of the expected outcomes when speccing a new system. Thermal controls are an important part of maintaining the correct temperature; there are various thermal control products available on the market, enabling you to maintain a comfortable environment regardless of building size.

一些应用程序所需的简单机电控制可能是所有的机电控制。其他情况可能需要多个区域更详细的控制和传感器。此外,可预测的时间表可能需要更新的控制,包括在到达设施之前的用于加热和冷却的人工智能或远程基于Web的控制。188体育在线官方188d金宝搏的网址

3.潜在的电气问题可能会影响系统的性能吗?

Today’s heating and cooling systems offer many benefits that aren’t available in older systems. However, most of the electronics in modern systems can create issues not found in electromechanical systems, such as a low voltage specification; if the specification isn’t met, motor life will shorten and cause the electronic component to malfunction.

When speccing a system that will use backup power, it’s important to verify that all incoming power sources meet the requirements of the heating/cooling system. Frequently, this means the power supply meets a combined variation in voltage and frequency of 10 percent, provided the frequency variation doesn’t exceed five percent of the rated frequency.

Preventative Maintenance Signs | Pelonis Technologies, Inc.

发布者Sam Pelonis|2014年9月29日3:48:00 PM |0 Comments

工业加热和冷却系统可以在生命周期中屈服于各种问188d金宝搏的网址188体育在线官方题。如果您的系统中的任何并发症无人看管,它可能导致较高的公用事业成本,损坏的零件和设备,或暴露于危险空气质量。在许多情况下,可以通过利用预防性维护技术来避免这些问题。

To comply with industry standards, heating and188d金宝搏的网址188体育在线官方冷却系统must undergo annual preventative maintenance; it is good practice to prepare for upcoming seasons, as different temperatures and moisture levels can adversely affect different systems.

Since operating and energy costs can accumulate as time progresses, it’s in the best interest of you and your customers to keep heating and cooling systems running as efficiently as possible. You should be conducting routine inspection to ensure all components are functioning correctly.

注意迹象

PH2207-L4当执行preventative maintenance, there are several common signs that you should always be on the lookout for.

  • Listen for any abnormal noises.If you hear sounds emanating from the system that seem out of the ordinary, that could mean fan blades or sheet metal panels are loose, and thus vibrating. Continuing to listen will helpidentify the noise’s origin; once you find it, thoroughly and carefully inspect the blades and motor.检查风扇和电机是否轻松旋转 - 如果它们不是,则需要立即替换组件。
  • Unusual odors could be a problem.部分检查过程涉及使用您的嗅觉。如果系统周围的空气似乎是霉味或发霉的,则有一些可能的解释:常设水可以在排水盘中建立;排水线可以堵塞或不正确地安装;可能会有导管泄漏;或碎片可以在空气管道内或附近。您可以使用电子泄漏探测器测试任何可疑区域。系统中的任何一种燃烧的气味都可以由松动的电气连接和过热零件引起。这是一个潜在的火灾危险,所以如果你闻到燃烧,你需要迅速行事。
  • 缺乏气流。Lack or airflow may indicate a problem. You’ll need to make sure fans are rotating smoothly; also, check for any type debris that could be obstructing the system. When heating and cooling systems have substantially low airflow, it can dramatically reduce the life cycle of compressors—in fact, this is a major cause of compressor failure.
  • Look for discolorations.One of the more obvious signs of wear in your system is any discoloration; this can signal corrosion on various parts and equipment. If you see any abnormally colored water building up, rust might be inside your system. These issues can also indicate a moisture imbalance within the system.

Always remain vigilant

When you are open to these common signs of wear, you can prevent several issues from afflicting industrial heating and cooling systems. Being attentive and using these guidelines will enable you to lower maintenance costs and prolong the service life of your parts and equipment.
