About Our R&D

CHILLKING® is known for innovation.  We are always looking for ways to make our systems more efficient.  Recently we designed a four stage chiller using two compressors, the chiller is for a low temperature hydrotherapy treadmill used to treat horses with leg injuries.  We also assisted a major university in the design and building of an energy efficient residential HVAC unit in Arizona.  The chiller/heat pump we designed was two stages of chilled water that made ice in the evening to use for cooling the house during the day.  The chiller had another stage that could boost the cooling system if it ran low on ice.  If you use refrigerants to "make cold" then you are making heat at the same time.  CHILLKING® designed the system to capture heat for heating the residence at night, it also had a reservoir for potable hot water for cooking and bathing.  CHILLKING® manufacturers chillers that can make multiple temperatures at the same time.  Most home HVAC doesn't need this technology but isn't it nice to know that your system is designed energy efficient by a company that is always pushing the edge. 


CHILLKING®'s are built using quality materials in Texas.  Our stainless steel reservoirs are built in house.  We have standard sizes however we can custom build any size.  Most of our competitors use plastic reservoirs.  Our evaporator is built in house by CHILLKING®.  The evaporator is the most important component in our chillers.  Our evaporators cost more to build but are very, very energy efficient.  The main reason our chillers perform so well is the evaporator.  Every CHILLKING® must exceed is base design size by 10%.  If you think we are calling our 11 ton a 10 ton, look again.  We use less energy than our competitors 10 tons while we produce 11 tons.  Very important numbers to check.  Our compressors are Copeland.  The workhorse of the industry.  Our pumps are American made and built to run forever.  We use very generous condensers.  Our controls aren't preset buttons, we use field adjustable safety controls.  Each chiller has a high pressure cut off and a low pressure cut off.  We use environmentally friendlier 410a and are experimenting with other refrigerants.  Our chillers operate in a wide range of temperatures from -30°F to 135°F, we can adjust to operate in ambient of 150°F and have built chillers for extremely cold environments.  The chiller is shipped ready to operate -30°F to 135°F with no adjustments.  Ready to go.  Our chillers are ETL listed to conform with all UL codes.  We use Intertek as our testing laboratory.

Air handlers

CHILLKING® has a large mix of air handlers.  The air handler delivers the air to the room or rooms depending on your system.  The most efficient is a small air handler in each room.  These small units can be ordered with their own temperature controller,  humidistat, motion sensor, infrared sensor and condensate drain or pump.  By using this type room zoning the only room being cooled is the occupied room.  A main controller can set perimeters that can't be exceeded by the zone controller.  

We also build the traditional air handler that requires ductwork.  These CHILLKING® air handlers can be ordered up to 20 tons.  The unit comes with a cold water HX and there is a slot for a hot water HX.  If you use a CHILLKING® heat pump/chiller, a boiler, furnace/boiler fired by chopped wood, or solar the design is the same for the air handler.  Add a plenum, attach ducts and you are ready to heat or cool.  There are various controls that can be incorporated with a ducted system to cool or heat by zone only.  Remember the chiller isn't like HVAC, you are storing the BTU's in the water, then the BTUs are transferred by the water.  In refrigerant evaporators in an air handler, you are always operating at maximum.  On a chiller you only use what is needed.  The cost per BTU drops drastically.

How it works

Every CHILLKING® must produce 110% of its rating during tests of 90°F to 95°F with LWT 45°F.  Residential units are tested at 45°F to 50°F because a cold heat exchanger(HX) removes more humidity and has more reserve BTU for cooling.  When possible we build our residential CHILLKING® Chiller as a multiple staged unit.  Most of the time HVAC doesn't need 100% of its capacity.  There are many times when 1/3rd would be plenty of AC.  A 6 ton chiller with three 2 ton refrigeration circuits will be much more efficient.  When the interior of the home warms up the thermostat senses the change in temperature and demands cold water for the air handler's heat exchanger and or multiple air handlers.  A water valve opens and cold water flows through so the heat and humidity is removed from the air by it blowing across and through the HX.  The warmed water returns to the reservoir and mixes into the reserve.  The compressor may or may not come on during the cycle.  Since the BTU's are stored in the water/propylene glycol there may be enough "cold" stored for this "demand cycle."  As the water temperature rises the thermostat will turn on stage 1, this stage will keep running until the set point is satisfied.  If more heat is added and the water temperature hits the next set point another stage will come on, then the next and so on.  The first stage may be on at 46°F and off at 45°F, the second stage may be on at 47°F and off at 45°F, and the third may be on at 48°F, off at 45°F.  There are many ways to stage chillers, for a residence it should be based on energy savings and comfort.  The wonderful thing about a chiller is how efficient they are at removing heat, they quickly pay for themselves. 

The water cooled HX is more efficient than an evaporator.  It is important to note here that an evaporator is a heat exchanger, it's is a refrigerant to air HX.  Some people call the HX in a chiller air handler an evaporator, this term is incorrect because there is no evaporating refrigerant.  In a normal refrigerant evaporator there are hot and cold spots.  The refrigerant flow is controlled by capillaries or a TXV, a small flow of liquid refrigerant enters the evaporator (an evaporator is an HX) and starts to absorb heat and causes the refrigerant to become a vapor or gas.  (There's no need to get into why and how at this time.)   As you can imagine a mix of liquid and vapor doesn't cover the evaporator equally so it isn't as efficient as cold water that covers the entire area equally.  The water under pressure fills every nook and turn and flows through. The evaporator becomes just slightly warmer as it exits the HX giving a much more even coverage, giving better heat exchange and moisture removal. 

Thermal Dynamics

There are pros reading this that will want one very important thing pointed out.  Cold is absence of heat.  This may sound quite simple and not necessary to point out but it is what air conditioning and heating is based on.  Cold is normal, heat is added.  Cold in HVAC is when heat is removed.  You cannot add cold, you can only remove heat.  I've had people say, "well when you add ice cubes to water you are adding cold."  They haven't really thought it through.  Ice cubes are created by removing heat to put water into a solid state.  When you drop them in warm water the temperature of the water becomes cooler because you are transferring heat from the warm water into the frozen water (ice) and it raises the temperature of the ice so it becomes liquid.  The entire process was heat removal.  It is much easier to understand all types of refrigeration once this concept is grasped.  

There is a measurement by which all refrigeration is calculated, BTU's.  It takes 1 BTU to heat 1 pound of water by 1°F in 1 hour.  All of our calculations are based on this.  Here's an example.  The water coming to our chiller is 80°F and we need 60°F water, the pump is flowing 30 gallons a minute and we want to change it 20°F in one hour.  We convert the water to pounds for one hour.  30 gallons x 60 minutes = 1800 gallons.  One pound of water weighs 8.34 pounds.  1800 x 8.34lbs = 15,012 pounds.  We have a target of 20°F temperature change, that's our Delta "T".  15,012 pounds x 20°F temperature change equals 300,240 BTUs.  Now we convert to tons, a ton of refrigeration is 12,000 BTU.
300,240 divided by 12,000 equals 25.02 tons.

One other thing people have a problem understanding is a heat pump.  CHILLKING® manufactures a "chiller" for lack of a better word, that produces heat.  It's a chiller in reverse.  When it is cold outside we gather heat from the atmosphere using a refrigerant and capture that heat in our water reservoir.  If it is above absolute zero (-459.67°F) there is heat.  As the temperature comes up there is more and more heat.  Many people wonder how a heat pump uses refrigerant to make heat when it's snowing outside and things are frozen.  It's simple, think of this, a single match burning is about 1 BTU.  Let's say it is 30°F outside and here we stand conducting an experiment in the cold with a single match in hand.  If we strike the match and place it into a box that is 8" x 6" x 3", we will be able to feel the box warm because of the 1 BTU of heat.  Now let's place the match into a huge box with an interior temp equal to outdoor ambient, this box is 10' x 20' x 8'.  We will not feel any heat from the 1 BTU match, we know it's there because we can see it burning.  If that BTU of heat remained in that room without transferring through the walls we could recover a portion of that BTU of heat.  The heat is captured in the refrigerant, compressed to a hot gas, then the heat is transferred to the liquid for use in heating the home.

The Working System and DIY or Turnkey

Please call CHILLKING® or our residential distributor.  I am installing the multi zone CHILLKING® in my new home.  I am zoning each room with heat and cold air.  Each room will have a small air handler custom built by CHILLKING®.  Currently the small zoned air handlers are manufactured for us.  We are designing our own line of zone handlers.  Those will be installed and tested in my new residence.  Well, it's new to me.  The current owners are paying $700 to $1,000 a month.  I expect to pay $150 or less.  The home is all electric.  I will report more in the months to come and I will post the photos and results on this page.  

All homeowners can save money on utilities with a CHILLKING® Residential Package.  In most locations and states the homeowner can DIY.  CHILLKING® has installers that travel the nation. If you want a turnkey system it can be quoted.  Imagine, no ducts!  Just a small water line to and from each zone handler.  

CHILLKING® has recently obtained www.chillking.ie.  Our new site will soon be up.  All CHILLKING® products are ETL rated to conform with UL codes.  Soon we will be EU CE listed.  CHILLKING® has a distributor in Ireland that will be shipping to other European locations.  Europe is big on DIY.  It is important to check local codes in both all countries.  In the U.S. Our chillers can be self installed by the homeowner because they are self contained.  No refrigerant to handle, no refrigerant lines to run.  Just a blue cold water line to the air handler/s and a red warmed water line returning to the chiller.  Very simple.  It is important to use licensed electrician for the electrical hook ups.  If the local code requires a licensed technician to install the system it is important to use a licensed technician.  Failure to follow local codes could void the warranties.
