You probably know that chillers are divided into two categories according to their condenser structure: air-cooled and water-cooled chiller categories. In this article, we will take a closer look at choosing cool air chillers and what to look for when buying a cool air chiller. Cool air chillers are made of compression units that work with copper pipes and aluminum fins by reducing the temperature of high temperature refrigerant gas using ambient air. However, cool air chillers have many features within them. Depending on the area used and the work situation to be done, the decision to choose a cool air chiller will also change. For this reason, when choosing a cool air chiller, you must consider many factors.
In terms of general characteristics, air-cooled chillers are less efficient than water-cooled chillers. However, in some cases, cool air chillers are preferred.
Now the question arises that when choosing and buying a cool air chiller, what points should be considered ?!
When choosing a cool air chiller, the characteristics of the area used and the capacity of the device used are taken into account. Where the area used is very cold and the temperature difference between day and night is very large, cool air chillers are preferred. However, in such cases, it should be considered whether to use devices with a minimum capacity or not. If there are low capacity appliances, it makes sense to prefer air-cooled chillers.
The height factor is the next thing you should pay attention to when buying a cool air chiller. In cool air devices, the capacity decreases with increasing altitude. So you have to consider this factor thoroughly.
If you are going to choose a cool air chiller, you should also consider how to control the chiller. Because devices that are easily controlled promise more efficient work and performance.
In cold air devices, the remaining capacity of the device is reduced by 1% per 1 ° C. This is an important point that will greatly affect your choice. At the same time, this change also affects the compressor and increases the power drawn by the compressor by 1%.
It is necessary to protect the devices as much as possible against high pressure, whether the air is cool or the water is cold. For this purpose, the amount of condenser air flow must be high. At the same time, low and medium pressure refrigerants should be preferred.
Again, in the group of air-cooled chillers, the values of evaporator pressure drop should not exceed 60 kPa as much as possible, and in the group that prefers the lowest steam pressure drop as much as possible.
The size of the chiller plays an important role at this stage. If you have a small business, keep in mind that chillers are often smaller in size than cold water chillers. In such cases, cool air chillers are generally preferred because they take up little space.
The issue of cool air chiller noise should also be considered. In places where noise is important, groups whose sound pressure does not exceed 75dBA at a distance of 5 meters in open space should be selected, and groups with low noise levels should be preferred.
Sheet metal parts and pieces Groups that are installed on the beach and exposed to the atmosphere of salinity and corrosion must have the relevant certificates to protect the external and internal components of the chiller. For example, if possible, a copper tube or copper fin should be selected.
The number of compressors of the selected chiller group and the number of refrigerant circuits must be written in the specifications.
When you consider the points to consider when buying a cool air chiller, you get cool air chiller systems that you can use for years with the same functionality and get maximum performance.
Remanufactured chillers offer a cost-effective alternative to business owners who are looking for creative ways to control operating costs. Buyers who are considering investing in a remanufactured chiller should understand the differences that exist between new chillers, remanufactured chillers and used chillers. When evaluating providers of refurbished chillers, prospective buyers should recognize that not all remanufactured chillers are created equal. Buyers should be sure to consider a manufacturer’s industry experience and commitment to quality.
There are three general categories of chillers available for purchase by suppliers. The category of chiller depends upon the date of manufacture, the degree of use, and whether any components have been replaced by an experienced technician. Below are the three general categories of chillers:
While used chillers may be available online at an attractive price, their components are often worn and there is often no guarantee that they will be in good working order. Professionally remanufactured chillers, on the other hand, have undergone a thorough inspection by a trained technician. Worn components have been replaced with new ones and a warranty is typically included with the purchase price.
Professionally remanufactured chillers can be built in accordance with desired specifications. Remanufactured chillers have undergone a thorough inspection by a trained technician. They have been completely tested and cleaned before they are reused by a new buyer. Below are some of the key elements of the chiller remanufacturing process:
Chillers that have been professionally remanufactured are ETL listed and evaluated in accordance to UL 1995 standards. This commitment to quality sets professionally remanufactured chillers apart from other pre-owned chillers on the market.
Chillers are a major investment for a company and they can be costly to ship and install. It is critical that purchasers make an informed buying decision when buying a remanufactured chiller. Most important, a remanufactured chiller should include a warranty – preferably the same warranty as a new unit. The absence of a defective parts warranty may be indicate that the chiller is no longer supported by the manufacturer, making the availability of replacement parts virtually impossible.
Purchasing a remanufactured chiller is a much different process than purchasing a new chiller. Buyers must be wary of people and fly-by-night companies that try to sell their damaged or malfunctioning chillers to unsuspecting online buyers in search of a low price. Ideally, prospective buyers should seek the following:
