Thermoelectric Air Conditioner Applications

WATER QUALITY MONITOR:

The system pictured below is used to automatically collect and analyze water samples for water quality monitoring purposes. The system can be powered from the grid or from the attached PV system. The TECA AHP-300 air conditioner is located within the enclosure and is used to keep critical internal components cool during the summer months.

COOLING GLOVE BOXES:

A customer manufactures a range of glove box systems for atmosphere control applications in clinical and industrial environments. TECA air conditioners are a vital component on a variety of the glove box models that this customer produces. Standard and customized versions of TECA air conditioners from the AHP-1800-Series are used to control the glove box temperature to below ambient. Clinical applications primarily revolve around cell and bacterial studies within cancer research, bio-fuels studies, sleep apnea, anaerobic microbiology research and clinical applications etc. Industrial applications include product weighing or assembly with humidity and temperature maintenance.

INCUBATOR COOLING / INSECT REARING CHAMBER:

Incubators used in the rearing of insects for research often experience thermal failures due to the acids inherent in the biology of the insects. The acidic environment that insects create can quickly corrode a standard, compressor-based cooling system- even if its copper coils are coated. High humidity adds to the problem because droplets of concentrated acid will collect on the cooling components. The solid-state nature of TECA’s thermoelectric air conditioners solves this problem offering reliability and virtually maintenance-free operation.

A published life science researcher from a local university contacted us because he experienced several failures from his compressor-based air conditioner units. He is raising flies in an incubator, and requires an accurate set point. The TECA Model AHP-1200 Thermoelectric Air Conditioner is the perfect solution. The air conditioner keeps the incubator to 18C as the customer requested. Using a remote, programmable temperature controller (TECA Model TC-3400) the customer is getting the accuracy he needs and the convenience he wanted from a remote controller.

 

UNIVERSITY RESEARCH LAB LASER COOLING:

A physics laboratory at a large university required cooling for their laser. The enclosure did not have any room for an air conditioner to intrude. The flush mounted (mounts external to enclosure) TECA Model FHP-750 was the right solution.

TECA Air Conditioners are available as Flush Mount (external to enclosure), Through Mount (half in, half out) and Internal Mount (mounts internal to enclosure) to serve applications wherever space restraints may exist.

 
LAB MEASURMENT EQUIPMENT:

A world's leading international supplier of equipment, controls and parts to glass container industry uses the peltier air conditioner model FHP-750XE in a statistical sampling and lab measurement product. A MiniLab Automatic Sampling installation works in conjunction with the production’s online inspection equipment and a Factory Process Control System.  The MiniLab Controller communicates to the Process Control System which then sends a container “request” to upstream online inspection systems equipped with mold number readers.  The “requested” containers are transferred to the MiniLab sampling conveyor using container ware selectors.

With broad-based expertise in glass container forming, glass conditioning, gob forming, ware handling, cold end inspection, refractory parts and quality assurance, the company's machines and systems are established as standard products worldwide. The FHP-750 has been working fine for them for years. Reasons for its selection are its reliability and ability to operate in high ambient temperatures.

 

RUGGEDIZED MILITARY APPLICATION:

Sometimes it just takes a long time to get to the heart of a problem. A “quick quote” for two thermoelectric air conditioners came into our sales team. It was responded to and followed up. The application was reviewed, a quote was made and an order placed. Only after did we learn that the hard requirements they were looking for were:1) Dual adjustable temperature control (heat and cool) 2) 28 VDC operation and 3) Military environment. Fortunately the selections within TECA’s enclosure air conditioner family are large. The military Contractor borrowed a unit from TECA’s loaner stock and based on that success, placed an order. It was then that we found a problem. It seems that the application was to cool some sensitive electronics out on a 200 meter DC input which caused droop in the input which in turn caused a ringing in the circuits. The new digital monitors being used were susceptible while the older tube monitors had no issue. Working with the customer it was determined that by changing the controller to a ruggedized PWM controller all problems were solved.
