USS Texas (BB-35): Butcher Shop
Tumblr media Tumblr media Tumblr media
The butcher shop onboard USS Texas (BB-35) was located on the main deck.
Tumblr media
The meat was stored in the refrigeration room on the 3rd deck and could hold 30 tons.
"As built, the ship had a significant ice making capability. They used large, low pressure CO2 compressors to make ice. The ice was used in a heat exchanger in which salt water was circulated through pipes. It was then piped to cool powder magazines and reefers (refrigerated compartments). The preferred refrigerant of the day was ammonia, but that was far too dangerous to use on a ship. A small leak could quickly and painfully kill crew. With CO2, it's not toxic, but you will gasp for air and hopefully have time to get away from it before smothering."
Informatiom from Tom Scott.

2024 to learn to use the new refrigeration technology technology to ensure the continuous freshness of vegetable food
With the development of modern society, refrigeration technology plays an increasingly important role in our daily lives. From home air conditioning to commercial refrigeration, from the medical cold chain to food processing, refrigeration technology is used everywhere. In this field, professional refrigeration technology has become the key to promote the development of the industry and bring comfort and convenience to our lives.
The importance of specialized refrigeration technology cannot be overstated. First of all, it provides a comfortable temperature for our living and working environment. In the hot summer, air-conditioning systems can bring us coolness and comfort, and the support and innovation of professional refrigeration technology is indispensable behind these refrigeration equipments.
Tumblr media
Secondly, specialized refrigeration technology also plays an important role in food preservation and healthcare. In food processing and refrigerated transportation, refrigeration technology can extend the shelf life of food and ensure its freshness and safety. In the medical field, cold chain transportation and refrigeration equipment ensure the quality of medicines and vaccines, and play a vital role in disease control and prevention.
The development of specialized refrigeration technology is dependent on technological innovation and continuous progress within the industry. For example, advanced compressor technologies such as Semi-Hermetic compressors, Scroll compressors and Screw compressors, as well as various types of condensing unit products, are all important components of specialized refrigeration technology. The continuous innovation and enhancement of these technologies has brought about a huge improvement in the performance, efficiency and reliability of refrigeration equipment, as well as a better user experience. Next, let's discover the various types of refrigeration compressor models:
Semi-Hermetic compressor, this compressor is compact, suitable for small and medium-sized refrigeration systems, with high reliability, easy maintenance and so on. The company's Semi-Hermetic compressor is widely used in commercial refrigeration and freezing equipment, industrial refrigeration equipment and other fields, well received by consumers.
Tumblr media
Scroll compressor, another product that has attracted a lot of attention is it. This compressor adopts advanced scroll compression technology, featuring smooth operation, low noise and high efficiency. It is widely used in air conditioning, heat pumps, commercial refrigeration equipment and other fields, and can provide reliable refrigeration solutions.
Tumblr media
Screw Compressor, this kind of compressor is suitable for large refrigeration system, with high efficiency and good stability, etc. Screw Compressor is widely used in industrial refrigeration, cold storage, cold chain logistics and other fields, which can provide very powerful refrigeration capacity.
Tumblr media
Reciprocating Compressor is also a common refrigeration equipment, which is used to inhale low-temperature and low-pressure vapors, increase their temperature and pressure through compression, and then discharge the high-temperature and high-pressure vapors. This type of compressor is commonly used in refrigeration systems, including domestic refrigerators, commercial cold storage equipment, air conditioning systems, industrial refrigeration equipment, and more. This type of compressor is usually characterized by simple structure, high reliability, large refrigeration capacity, etc., and is suitable for refrigeration systems of various sizes.
Tumblr media
Condensing Unit, this is in addition to compressor products, various other types of condensing unit products. These units are compact, stable performance, can be widely used in commercial refrigeration and freezing equipment, catering cold storage and other occasions, can provide comprehensive refrigeration solutions.
Tumblr media
In addition to the above, there are more 2024 new refrigeration technology products waiting for you to discover, now immediately click to learn more: https://youtu.be/SlXrf5VmqsE?si=u7y4viIEIax98Oi2

A spring house is a small building constructed over a spring. While the original purpose of a springhouse was to keep the spring water clean by excluding fallen leaves, animals, etc., the enclosing structure was also used for refrigeration before the coming of ice delivery and, later electric refrigeration.
The water of the spring maintains a constant cool temperature inside the spring house all year. Food that would otherwise spoil, such as meat, fruit, or dairy products could be kept there. It was also safe from animals as well. Springhouses often also served as pumphouses, milkhouses, and root cellars.

Squeezable Metal Offers a Greener Approach to Refrigeration
A system built around a metal that gains and loses heat when compressed could lead the way to the commercialization of chemical-free refrigeration technology. 
[...]
Refrigeration systems that use materials that cool in response to an applied electric, magnetic, or mechanical force offer environmentally friendly alternatives to the greenhouse-gas-leaking ones found in most homes and factories (see Feature: In Hot Pursuit of 21st Century Cooling). Now researchers have demonstrated a cost-effective, scalable version of one of these so-called “caloric cooling” systems [1]. Their approach, which uses a material that responds to a mechanical force, exceeds performance records set by methods that rely on magnetic fields. The researchers say their technology is also much less expensive to make and to operate and could be ready for commercial use within a year.

A recent playthrough of Dragon Age Inquisition gave me a line of dialog that sparked a bizarre question.
Sera was speaking in her usual childlike demeanor + British accent combo, and was saying something about superstitious reactionary excuses people use to justify violence. In the line there is a supporting part of dialog for the "children that they DON'T EVEN HAVE go missing!" banger of an ending, in which Sera mentions the example of blaming milk spoiling as an example.
I know ice magic exists in the setting and maybe I'm forgetting about a deep freezer existing in some butcher shop somewhere in the massive expanse in the Dragon age series-but refrigerators wouldn't exist for the historical context its based on. I got an image in my head of a peasant woman getting accused of witchcraft because she made the villagers milk go bad, and was struck with the curiosity to whether this particular thing actually occurred in our history? Milk going bad when your a medieval peasant (or something historically accurate that I'm ignorant of rn) with no concept of refrigeration is going to happen a lot...
But there i am again assuming things, there very well might be some form of rudimentary method to preserving milk from animals akin to refrigeration, but still milk going bad seems so mundane yet outlandish for a reason to witch hunt someone.
