Can Automotive Refrigerant and Household Refrigerant Be Used Interchangeably?

Automotive refrigerant and household refrigerant cannot be used interchangeably, as they are different types of refrigerant media. Do not cross-fill them. Below is additional information regarding automotive and household refrigerants: 1. Older Household Refrigerant: If it is a very old household air conditioner, the refrigerant used is different from that in automotive air conditioners. Older household air conditioners use R12, which is an obsolete refrigerant. 2. New Household Air Conditioners: New household air conditioners mostly use R134. This is a newer refrigerant, primarily due to environmental concerns. In fact, mixing the two refrigerants is not a problem, except that the high-pressure side may be slightly higher, but the compressor oil must be replaced. Currently, automotive air conditioners use either R134 or R407—407 is rare, while 134 is more common. R407 is a relatively new refrigerant. Modern automotive air conditioners use the same refrigerant as household air conditioners.

What does the fishbone line on the highway mean?

Fishbone lines on highways usually appear near ramps, indicating that drivers should slow down because the upcoming intersection is relatively narrow. There are two types of fishbone lines: 1. Dashed fishbone lines: Drivers can change lanes or cross the lines without penalty, but they should still slow down when seeing such markings. 2. Solid fishbone lines: Crossing these lines is prohibited and may result in a 6-point penalty on the driver's license. In such cases, drivers should simply continue straight ahead without worry. When approaching a ramp with fishbone lines, slowing down and driving safely will prevent fines or point deductions. Highway signs and markings contain significant knowledge, but their sole purpose is to ensure driver safety and maintain traffic order. It's important to familiarize oneself with these traffic signs to avoid fines, point deductions, or more severe consequences due to ignorance.

How are tolls charged when exiting the highway after the free period?

Exiting the highway after the free period will incur a vehicle toll, which is calculated based on the exit time. According to the notice from the State Council on the implementation plan for exempting tolls for small passenger vehicles during major holidays, the toll-free periods for small passenger vehicles during major holidays are as follows: 1. For ordinary roads, the toll-free period is determined by the time the vehicle passes through the toll booth lane; 2. For highways, the toll-free period is determined by the time the vehicle exits the toll booth lane at the highway exit. The highway toll is calculated from the time the vehicle enters the starting station before the end of the toll-free period at midnight, not based on the distance traveled from midnight. The toll-free period is determined by the time the vehicle exits the highway toll booth lane.

How long does it take to drive 30 kilometers?

30 kilometers of driving takes half an hour when driving at a speed of 60 kilometers per hour. If driving in the city, including waiting at traffic lights and traffic congestion, driving 30 kilometers may take up to an hour. The time taken to cover the distance can be affected by many factors, such as road conditions. If it's a direct road with little traffic, the journey will be much faster. If the road conditions are more complex, the same distance will naturally take longer. Additionally, the driver's habits also play a role—some prefer driving at higher speeds, while others drive more cautiously, resulting in slower travel times.

What is the free time for highways on October 1st?

October 1st highway free time is from 00:00 on October 1st to 24:00 on October 8th. The highway toll-free period is determined by the time when the vehicle exits the highway toll lane, which means that if you enter the highway during the toll period and exit during the free period, you will not be charged. Conversely, if you enter the highway during the free period and exit during the toll period, you will be charged. However, drivers who need to cross provinces must pay attention: if you pass the provincial boundary toll station before 00:00 on the 1st, you will be charged. Therefore, it is recommended that drivers arrange their time in advance. If not possible, they can rest at a nearby service area and wait until 00:00 to pass the toll station, which will then be free.
