One pump circulates the chiller’s evaporator to keep the chiller’s internal tank at the target set point temperature. The other pump pulls out of the chiller’s internal reservoir, circulates to your downstream application, and returns back to the chiller’s internal reservoir. This is a single condenser system that can contain up to two circuits. The expansion valve holds back the refrigerant and maintains the high pressure of the condenser. Inside the expansion valve, a small orifice allows a restricted amount of refrigerant to continue to flow. As it flows through this restriction it reaches the low pressure side of the valve. This sudden pressure drop allows the refrigerant to expand from a liquid into a liquid/vapour mixture. The same amount of refrigerant flows through, it just has more space so it expands to fill this gap. Energy cost remains a major consideration in any powered equipment. While the chiller has direct impact on energy usage, there are other factors to consider.
A chiller equipped with a fixed speed compressor controls the temperature of the water traditionally with simple on/off of the compressor. This means that when the compressor runs, it runs at the designed load regardless of the process needs. A more advanced option is a hot gas bypass which technically keeps the chiller running but bypasses the hot gas if no cooling load is needed. This avoids the on/off of the compressor but results in a waste of energy since no cooling is required from the process. The Delta T Systems “VS Chiller” with the variable speed compressor operates effectively between 10% and 100% of its rated capacity. This means a 10 ton chiller can operate very efficiently as a 1 ton as well as up to a 10 ton chiller. This new design applies proven, variable speed “green” compressor technology from the HVAC industry to produce up to a stunning 50% energy savings over traditional hot gas bypass regulation. These energy cost savings can pay for the chiller investment in less than 3 years. In addition, utility companies may offer purchasing incentives and rebates.

This boils the water out of the absorption liquid at a high pressure. The next step is sending the refrigerant water vapor past a condenser coil where the heat is rejected and the water vapor is phased into a high pressure liquid. Then the high pressure liquid is passed along to the lower pressure evaporator where adiabatic flash evaporation returns the water to a gas. The last step is the concentrated absorption liquid is sent back to be recombined with the lower pressure water vapors coming from the evaporator. Vapour compression chillers use an electrically driven mechanical compressor to force a refrigerant around the system. There are two sub categories for vapor compression chillers which are water cooled or air-cooled chillers and we’ll look at these shortly. Microtech controls and sensors are operational and functioning properly. There is a BacNet IP card installed and operational All compressors operate properly. 100 PSI low pressure and 132 High pressure with liquid refrigerant present in both circuit liquid lines. The controls indicate that there is 2185 operating hours on each circuit with 2575 starts.
Air cooled and water cooled chillers have many things in common. They both belong to the same vapor compression chilling family, and they both use an electronically driven mechanical compressor to force refrigerant around the system. The main difference between the 2 is how unwanted heat is ejected from the system. Water cooled chillers pump water through a sealed condenser and disperse it through a cooling tower. Air cooled chillers use fans to force cool air across the condenser. Cost is one of the important factors when deciding between air cooled or water cooled chillers.
This chilled fluid is then capable of removing heat from machinery, food, or other equipment and continuously run back through the chiller. There are other things that can be added to a chiller in order to make it better suited for your business. Split chiller systems let you keep the refrigeration and fluid components inside, and the condenser can be outside. This will allow you to meet specific weight distribution and space requirements. More heat exchangers can be attached to start cooling a liquid before it goes in your chiller, which is something dairies often need. Always consult an expert about your chiller to see if you need any customization. A typical water-cooled chiller uses recirculating condenser water from a cooling tower to condense the refrigerant. A water-cooled chiller contains a refrigerant dependent on the entering condenser water temperature , which functions in relation to the ambient wet-bulb temperature.
This unit is 460 volt, and has two scroll compressors, a brazed plate heat exchanger, Carrier’s quiet fans, and Comfort-Link Controls. This unit is outdoor weather rated, although we have seen users run them indoors also. This chiller was run and tested at our Massachusetts facility, where we ship about 100 chillers per year from. If you plan on running this unit for year round process cooling, AND you are in a cold climate, a low ambient VFD drive option for the condenser fans will be required. Offered by KIG in October 2019 was this pristine 2012 Thermal Care NQ series Air Cooled Chiller. It is 460 volt 3 phase power, has dual scroll compressors, the newer R410a refrigerant, and 20°F to 80°F fluid/glycol temperature range. This is an indoor chiller, yet the exhaust can be ducted outside if you choose, as it was at its prior location. This unit is made by Thermal Care and the case was re-branded through IMS . We have provided dozens of these Thermal Care units over the years, and they are well-built true workhorses. Arrived at KIG in April 2020 was this nice pre-owned Koolant Koolers / Dimplex Thermal 5 ton Air Cooled Chiller.
Portable Air has one of the largest air-cooled chiller fleets in the industry. Our vast selection of portable, trailer-mounted air-cooled chiller units is guaranteed to increase your productivity resulting in less downtime for your project. Air-Cooled Chillers from Budzar Industries are engineered, designed and manufactured to meet your exact requirements and in addition, air-cooled chillers tend to be easy to install and require little maintenance. These conservatively calculated energy savings can be much higher because most chillers are selected based on the peak usage time of the year which means the chiller is oversized for the average usage. The condenser is a configuration of horizontal pipes through which hot refrigerant runs. The compressor provides the driving force for moving the refrigerant around the system. Three of them use positive displacement to create pressure, and the fourth creates pressure with centrifugal force. Multi Temp Chillers require a pump to move water through the heat exchanger at all times.
These cooling coils transfer sensible heat and latent heat from the air to the chilled water, thus cooling and usually dehumidifying the air stream. Chilled water temperatures can range from 1 to 7 °C (34 to 45 °F), depending upon application requirements. Chiltrix uses a variable speed pump for the hydronic loop circulation. When full water flow is not needed due to off-peak capacity requirements, the water pump slows down and uses less energy. The variable speed pump and variable speed compressor work in tandem with the system controller using a special algorithm to keep the compressor and pump both working at the optimum speed. The variable speed condenser fan is controlled in a similar manner. This allows all of the consumers of electrical power within the chiller to operate at the lowest power level to meet the current load. Dynamically controlling the water pump speed and compressor speed independently of each other helps us to achieve the highest levels of performance. In addition, Chiltrix offers DC-Inverter indoor fan coil units, further reducing electrical power consumption . Air cooled chillers are typically located in mechanical equipment rooms or in an area of the building that is close to the spot it is cooling.
The users don’t change it, otherwise, it will cause serious problems. Don’t touch any electrical components except the switch includes an emergency switch. 6.8.2Turn off service valves of the inlet and outlet of the compressor. The refrigerant filler is connected into the low-pressure side filling connector, and connect pressure gauge at low pressure and high-pressure side. In the ice-freezing area in winter, the water has to be completely discharged from the condenser to avoid freeze to split accidents. if find oil color becomes black, or copper pieces in the oil, oxygenated impurity, the lubricating oil must be replaced with the same model after clean the oil filter, and bottom of the oil tank. The compressor has been filled with lubrication before leaving the factory. Finally, check controllers setting values of the screw chiller t to finish the testing and inspecting. The PH value, conductivity, chlorine ion, and sulfur ion have to meet TopChiller standard requirements.
You might need to use chillers with multiple compressors that can work independently from one another so that if 1 compressor fails the chiller can still remain partly operational. Instead you should use multiple chillers, in parallel, of different sizes to meet the changing seasonal load at optimal performance with redundancy built in. For example you have a building with a cooling load of 2,200 Tons, then you should use combinations such as two 1,200 ton chillers or two 900 tones and a 500 ton or a 1,000 ton and two 700 ton chillers etc. Vapor absorption chillers will use a heat source to move the refrigerant around the system rather than using a mechanical compressor. The refrigerant in these chillers move around between areas of different temperature and pressure. Arrived in March 2014 to KIG were four immaculate Trane RTAA 125 ton chillers. Removed from a local Data Center where it was used relatively minimal, and the Data Center has been shut down. Units are in pristine condition, have been expertly maintained, and have VFD low ambient option for year round operation. Has variable speed fan drive LOW AMBIENT option ideal for year round operation / process cooling. Arrived at KIG in July 2015 for refurbishment and testing was this solid Advantage 10 ton Air Cooled Chiller.
