Scroll Compreor

 

A compressor is a piece of machinery inside your hvac unit that compressor gaseous refrigerant so that it can pass through your refrigerant coil and be sent into your home to cool the air. A scroll compressor is a specific type of compressor that works by rotating pieces of metal instead of operating like a piston in an engine.

Why is a scroll compressor better? What makes AGKNX being the best Scroll Air Compressor Suppliers in China?

Scroll compressors have fewer moving parts which makes them more energy efficient, quieter, and less prone to failure. This generally provides a better experience to the homeowner as the system will cost less to operate and repair, and will produce less noise than a traditional compressor.

Our scroll compressors are apt for all kind of industrial use

Our designed scroll compressor operates by using two scrolls, one stationary and another orbiting around to create mechanical energy. Due to which the compressors are apt to be used in many different industries including food processing plants, breweries, chemical plants, natural gas pipelines, and more.

We provide a scroll compressor that can withstand high temperature

Agknx’s researchers and designers have redesigned the scroll compressors which have made them an effective solution to cool down your business with minimal noise pollution. The newly designed products also have the ability to work at higher temperatures than other types of compressors, meaning they’re perfect for industrial environments where high heat is common. So, using our scroll compressors will keep your company running smoothly no matter what you throw at it.

How a scroll compressors work

A scroll compressor actually consists of two scrolls or spirals. One scroll is moving, whereas the second one is fixed (attached to the compressor body). The first scroll orbits (rotates) in a path defined by its mating fixed scroll. The orbiting scroll is connected to the compressor’s crankshaft.As a result of the scroll’s movement, gas pockets are formed between the two scrolls. At the outer part of the scrolls, the pockets suck in gas and then move towards the center of the scroll, where the compressed gas is discharged. As the gas moves into the continuously smaller internal pockets, both its temperature and pressure are increased. Thus a desirable discharge pressure is achieved by the motion of the compressor scrolls.

how scroll compressors work

Figure 1 – Diagram showing how a scroll compressor works

Structure of a scroll type compressor

Scroll compressors are fully hermetic (enclosed in the compressor’s shell, which is usually a cylindrical welded steel shell). Majority of scroll compressors used in refrigeration and HVAC services are of vertical orientation, with the scroll sets typically installed on the upper part of the motor shaft.

Typical structure of scroll compressors

Figure 2 – Typical scroll compressor diagram

Using valves in a scroll compressor

Normally, suction or discharge valves are not used in these compressors. But dynamic discharge valves are preferred at the compressor discharge, when operating at high differential pressure values. In such scenarios, having a dynamic valve at the discharge increased the efficiency of operating the compressor. For example, scroll compressors operate at high differential pressure, in case of refrigeration applications. In such cases dynamic discharge valves are preferred.

But in other cases, for example – air conditioning, having a discharge valve actually results in pressure losses, reducing the efficiency. Hence these are normally not preferred.

Advantages

Scroll type compressors are inherently more efficient compared to other types of compressors for many reasons:

  •  The absence of pistons for gas compression enables scroll compressors to reach 100% volumetric efficiency, leading to reduced energy costs.
  • Re-expansion losses, a typical feature of each piston stroke encountered in reciprocating models, are eliminated. In addition, valve (ports) losses are eliminated, since suction and discharge valves (ports) do not exist.
  • Furthermore, due to the absence of several moving parts, scroll compressors are considerably quieter in operation compared to other types of compressors, like for example reciprocating type ones. Scroll compressors typically make 5 to 15 dBA lower noise than other compressor types.
  • Due to lower vibration and noise, they do not need spring suspensions.
  • Fewer moving parts, lower vibrations and less friction also means that these compressors are more durable.
  • Their weight and footprint are considerably smaller compared to other bulkier types of compressors in use nowadays.
  • Gas pulsation is also minimized, if not eliminated and consequently, they can operate with less vibration.

Disadvantages

  • Being fully hermetic, perhaps the biggest disadvantage of scroll compressors is that they are generally not easily repairable. They cannot be disassembled for maintenance.
  • Many reciprocating compressors are tolerant on rotating in both directions. This is usually not the case for scroll compressors.
  • Incremental capacity control on systems with several scroll compressors has proven several times to be problematic as well.

Applications

Since their introduction, scroll compressors have been successfully used in applications involving food and fruit refrigeration, truck transportation, vacuum pumps, marine containers as well as residential and small to medium scale commercial air-conditioning applications.

Selecting a scroll compressor

When selecting a compressor you can either go for single phase or 3-phase motor for the compressor. It will completely depend on what kind of electricity connection is available. Normally, single phase connections are available. If 3 phase connection is available, then the three phase motor is considerably more efficient.

Next, you should consider the differential pressure and flowrate parameters. There are different scroll compressors available in the market, having different combinations of differential pressure and flowrate values. You should select the one which covers your requirements of certain minimum differential pressure at given flow rate.

Next, you can look at secondary parameters like the noise level etc. depending upon where the compressor is going to be used. If it is going to be used in a residential air conditioner, you will prefer to use a model with lower noise levels.
