環保型製冷劑早在2013年就開始在國內外使用開來,世界各國也都在逐步淘汰多種傳統製冷劑,提倡使用環保製冷劑。當然了,環保型製冷劑主要也就是體現在“節能環保”,未含有“Cl”元素的新型環保型製冷劑也正是未來製冷機行業發展的新方向。
The environment-friendly refrigerants began to be used at home and abroad as early as 2013. Many countries in the world are phasing out a variety of traditional refrigerants, and advocate the use of environmentally friendly refrigerants. Of course, the environmental protection refrigerant is mainly embodied in the "energy saving and environmental protection", which does not contain "Cl" element of the new environment-friendly refrigerant, is also the new direction of the development of the chiller industry in the future.
 
新型環保製冷劑R 134a與R12製冷係統的主要區別:
The main difference between the new type of environmental refrigerant R 134a and the R12 refrigeration system:
 
1、存放製冷劑R134a的容器為淺藍色,而存放R12的容器為白色。
1. The container for the refrigerant R134a is light blue, and the container for R12 is white.
 
2、R134a製冷係統連接軟管是用橡膠和尼龍特製的,並且在其處部有汽車工程學會的印記(S.A.E.#J2196);而 R12製冷係統連接軟管常用一般橡膠管。
2, the connection hose of R134a refrigeration system is specially made of rubber and nylon, and there is a mark of automobiles engineering society at its part (S.A.E.#J2196), while R12 refrigeration system connection hose is usually used as general rubber tube.
 
3、R134a新型製冷係統連接管有顏色標記(低壓管是藍色帶黑色條紋,高壓管是紅色帶黑色條紋,普通管是黃色帶黑色條紋)而R12製冷係統連接管則無標記。
3, R134a new refrigeration system has color markings on the connecting pipe (low pressure tube is blue with black stripe, high pressure tube is red with black stripe, common tube is yellow with black stripe), and R12 refrigeration system connection pipe is marked.
 
4、R134a新型製冷劑入口處使用的是快速接頭,而R12製冷係統使用的是螺紋接口。
4, the R134a new refrigerant entrance is used in the rapid joint, and the R12 refrigeration system uses the threaded interface.
 
5、新型製冷劑R134a製冷係統連接軟管與儀表的接頭具有1/2in英寸螺紋,且高壓口的接頭比低壓口的大;而R12製冷係統連接軟管與儀表的接頭具有7/16in螺紋。
5, the connection between the new refrigerant R134a refrigeration system connection hose and the instrument has 1/2in inch thread, and the joint of the high-pressure port is larger than that of the low pressure port. However, the joint of the R12 refrigeration system connecting the hose and the instrument has 7/16in threads.
 
6、與R12製冷係統相比新型製冷劑R134a製冷係統具有較高的壓力和溫度,需要較大的冷卻風扇 。
6. Compared with the R12 refrigeration system, the new refrigerant R134a refrigeration system has higher pressure and temperature, and a larger cooling fan is needed.
 
新型製冷劑R134a的優勢:
The advantages of the new refrigerant R134a:
 
1、新型製冷劑R134a不含氯原子,對大氣臭氧層不起破壞作用;無溫室效應。
1. The new refrigerant R134a does not contain chlorine atoms, which does not destroy the ozone layer in the atmosphere; there is no greenhouse effect.
 
2、新型製冷劑R134a具有良好的安全性能(不易燃,不爆炸,無毒,無剌激性無腐性)。
2, the new refrigerant R134a has a good safety performance (non flammable, explosive, toxic, non irritating non corrosive).
 
3、新型製冷劑R134a的傳熱性能比較接近,所以製冷係統的改型比較容易。
3. The heat transfer performance of the new refrigerant R134a is close, so the modification of the refrigeration system is easy.
 
4、新型製冷劑R134a的傳熱性能比R12好,因此製冷劑的用量可大大減少。
4. The heat transfer performance of the new refrigerant R134a is better than that of R12, so the dosage of refrigerant can be greatly reduced.
 
5、凝固點低,蒸發潛熱更大,使單位時間內降溫速度更快。
5, the freezing point is low, and the latent heat of evaporation is greater, which makes the cooling rate faster in unit time.
 
6、壓縮機壓力比小,使壓縮機工作更輕鬆,延長壓縮機使用壽命。
6, the compressor pressure ratio is small, make the compressor work easier and prolong the service life of the compressor.
 
7、在不改變空調任何結構部件的情況下,可直接進行替代。
7, without changing any structural parts of the air conditioner, it can be replaced directly.
 
8、低係統運行成本,在空調係統運行時,保證製冷量的同時,節電率達到20%--35%左右。
8. Low system operating cost. When the air conditioning system runs, the cooling rate is guaranteed, and the power saving rate is about 20%--35%.
