Question: What American manufacturer of heating and cooling appliances purchased the rights in 1925 to be the only refrigerator manufacutrer in America?

Context paragraphs:
Martin Naughton (businessman): Martin Naughton, KBE (b. 1940 in Dundalk, County Louth), an Irish entrepreneur, founded Glen Electric in August 1973 with a small manufacturing facility employing just ten people in Newry, County Down, Northern Ireland.  In 1977, Dimplex, the leading brand in the UK electrical heating market was acquired by Glen Electrics forming the Glen Dimplex Group.  The company set out acquiring further businesses across the UK with Morphy Richards, the market leader in small domestic appliances in 1985 followed by Blanella, a manufacturer of electric blankets and Burco Dean Appliances, a manufacturer of products for the catering industry, all in the same year.  The 1990s saw the company forge its powers of acquisition and strategic business thinking to acquire further businesses across Europe and beyond.  An engineer by profession, Dr. Naughton has overseen his company to become the world's largest manufacturer in domestic heating appliances.  His company has plants in the Republic of Ireland, the United Kingdom and North America.  His business has more than 8000 staff and 22 manufacturing facilities with annual sales of around $1.6 billion.  Naughton's stake in the company is worth around £273 million with other investments including an art collection, property in Dublin and shares in the Merrion Hotel Group and the Sunday Tribune newspaper.  He was awarded with an honorary degree (Doctor of Science) for his services to promote business in Northern Ireland.

Thermoelectric cooling: Thermoelectric cooling uses the Peltier effect to create a heat flux between the junction of two different types of materials.  A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.  Such an instrument is also called a Peltier device, Peltier heat pump, solid state refrigerator, or thermoelectric cooler (TEC).  It can be used either for heating or for cooling, although in practice the main application is cooling.  It can also be used as a temperature controller that either heats or cools.

Home appliance: Home appliances are electrical/mechanical machines which accomplish some household functions, such as cooling/heating, cooking or cleaning.  Home appliances can be classified into:

Midea Group: Midea Group () is a Chinese electrical appliance manufacturer, headquartered in Beijiao, Shunde, Foshan, Guangdong.  As of 2013, the firm employs approximately 100,000 people in China and overseas across 21 manufacturing plants and 260 logistics centers across 200 countries.  Midea Group is listed on Shenzhen Stock Exchange since 2013.  It has been listed on the Fortune Global 500 since July 2016.  Midea produces wide ranges of lighting, water appliances, floor care, small kitchen appliances, laundry, large cooking appliances, and refrigeration appliances.  It also has a long history in producing home and commercial solutions in air conditioning and heating (HVAC).  In the summer of 2016, Midea made a highly publicized move to acquire German robotics company KUKA.

Baltzar von Platen (inventor): Baltzar von Platen (24 February 1898 – 29 April 1984), together with Carl Munters, was the inventor of the gas absorption refrigerator in 1922 while they were both Swedish engineering students at the Royal Institute of Technology in Stockholm, Sweden.  The technique produced "cold" from a heat source such as propane, electricity, or kerosene.  In 1923 production by AB Arctic began.  In 1925 AB Arctic was purchased by Electrolux, which began selling them worldwide.  Servel purchased rights to manufacture the refrigerator in 1925 and was the only U.S. manufacturer for many years.  Von Platen was awarded the Franklin Institute's John Price Wetherill Medal in 1932.

Warm Air Research House: The Warm Air Research House is a historic house and research facility located at 1108 W. Stoughton St. in Urbana, Illinois.  Built in 1924, the house served as a warm-air heating research facility administered jointly by the National Warm-Air Heating and Ventilating Association and the University of Illinois Department of Mechanical Engineering.  Prior to the 1920s, the American heating industry had few formal testing procedures for their products, and home heating through warm-air ventilation ducts was still considered a novel concept.  The National Warm-Air Heating and Ventilating Association began to test heating methods and systems in the Department of Mechanical Engineering's laboratories, but it eventually needed a model house in which to test its domestic heating systems.  The two organizations commissioned the large Colonial Revival residence, which was designed by architect Loring Harvey Provine and graduate student Clarence Andrew Kissinger.  Beginning in 1932, research on air conditioning and cooling systems was also conducted in the house.  Following World War II, the facility became less useful due to the shrinking size of new American homes, and the university sold the house in 1946.  Some of the technologies developed in the house include storm windows, forced-air heating, and heating duct size and positioning.

Servel: Servel was an American manufacturer of heating and cooling appliances, founded in 1922.

Absorption refrigerator: An absorption refrigerator is a refrigerator that uses a heat source (e.g., solar energy, a fossil-fueled flame, waste heat from factories, or district heating systems) to provide the energy needed to drive the cooling process.

International Mechanical Code: The International Mechanical Code (IMC) is a convention concentrating on the safety of heating, ventilation, and air conditioning systems.  It is published by the International Code Council (ICC) through the governmental consensus process and is updated on a three-year cycle to include the latest advances in technology and safest mechanical practices.  The current version of this code is the 2012 edition, with the 2015 edition slated for release in 2015.  The IMC protects public health and safety for all building heating, cooling and ventilation related design, installation and inspection by providing minimum safeguards for people at homes, schools and workplace.  Fuel burning appliances, cooling systems, heating systems appliance venting, location and protection of appliances and many other such issues are addressed in the IMC.

Coefficient of performance: The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work required.  Higher COPs equate to lower operating costs.  The COP usually exceeds 1, especially in heat pumps, because, instead of just converting work to heat (which, if 100% efficient, would be a COP_hp of 1), it pumps additional heat from a heat source to where the heat is required.  For complete systems, COP calculations should include energy consumption of all power consuming auxiliaries.  COP is highly dependent on operating conditions, especially absolute temperature and relative temperature between sink and system, and is often graphed or averaged against expected conditions.
