Pulse Width Modulation (PWM) is a control technique used in HVAC systems to regulate compressor activity and maintain desired temperature settings efficiently. In a typical scenario, a 15-second cycle operating at 50% capacity would involve the compressor pumping or “compressing” for 7.5 seconds, followed by a non-pumping?period of 7.5 seconds. For higher load requirements, such as 80% capacity, the cycle adjusts to 12 seconds of pumping and 3 seconds of non-pumping. This modulation approach allows for precise control over temperature, mirroring methods used in SCR heating systems and is straightforward to manage. Visit HVAC-TV Today! https://lnkd.in/dqupQJw2?

The four way reversing valve is a four-port valve that has a slide mechanism in it. The position of the slide is determined by a solenoid that is energized in one mode of operation and not the other. The position of the slide also determines the mode of system operation. Most heat pump systems are designed to operate in the heating mode when the solenoid is not energized. This is referred to as failing in the heating mode. For the remainder of this text it will be assumed that the heat pump system will operate this way. This may not always be the situation, so be sure to check each individual system being worked on. The position of the slide when the solenoid is energized and the system is operating in the cooling mode. Typical reversing valves have one port isolated on one side and the remaining three ports on the other. The isolated port is where the hot gas from the compressor enters the valve. Depending on the position of the slide, the hot gas will be directed to either the outdoor coil or the indoor coil. In either case, the coil that accepts the hot gas from the compressor is functioning as the condenser coil. Smaller heat pump systems utilize smaller, direct-acting, four-way reversing valves. "Direct-acting" implies that the solenoid provides the force needed to change the position of the slide in the valve. On larger systems, additional help is needed to move the slide. Valves in these systems are referred to as pilot-operated reversing valves. See more articles like this on our New Insight Partners HVAC blog! https://lnkd.in/eQJnnedq

THE FOUR WAY | Ever wondered how your home or business stays warm in the winter and cool in the summer? If you have a heat pump, its all thanks to this special part called the “four-way reversing valve”. The four-way reversing valve is like a magic switcher inside your business or home's heating and cooling system. Imagine that it has a little sliding door that moves back and forth. When the door slides one way, it makes your home cool in the summer. When it slides the other way, it makes your home warm in the winter. It's like a secret passage that sends hot air where you need it…AKA: “heat pump” for pumping the heat one way or the other! Pretty neat right? #heatpumps #hvac

Learn about the essential components of HVAC systems and how they collaborate to maintain comfortable indoor environments. Explore the functions of air handling units (AHUs), such as air dampers, filters, cooling coils, heating coils, humidifiers, and mixing chambers. Gain insights into the advantages and limitations of AHUs, along with alternative solutions like make-up air units (MAUs) and recirculation units (RCUs) for larger spaces. Understand the pivotal role of chillers in producing chilled water for cooling purposes, including the operation of air-cooled and water-cooled chillers. #HVAC #airhandlingunits #chillers #indoorcomfort

Here's a quick tutorial on your condenser and its crucial role in your HVAC system. The compressor pumps refrigerant through the system, absorbing and releasing heat to keep your home cool. If you notice high pressure readings, it could indicate a blockage in the metering device, preventing proper refrigerant flow.

?? RIFT Actuators x Fire Suppression A common question that we receive from our customers is 'Can your Actuators facilitate our project given the industry that we operate in ?'. The answer to that question is 'yes we can!' we manufacture and supply to a whole range of industries across the globe. The beauty about our RIFT Actuators in particular is that we offer a wide range of optional features that will benefit each industry in its own way. We can tailor towards almost any application and system if it has the ability to be automated. Recently we had a customer in the Fire Suppression industry that required an automated process to link with their Priority Demand System (PDS). This system will typically be found in high rise buildings/apartments and will restrict water flow utilising a Priority Demand Valve (PDV). In the event of a fire, it's crucial to restrict the water flow so that there is adequate water pressure readily available to be used by fire sprinkler systems in the aim to extinguish any fires. This is just one of the applications within Fire Suppression where our RIFT Actuators can be used to automate/regulate this process. If you're looking for a SMART Electric Actuator that can do almost anything in relation to automation, please feel free to contact a member of our team using our contact information below and we will ensure to get back to you as soon as possible. ?? - [email protected] ?? - +44 (0) 1684 303018
