Whether the set temperature dt can be reached

The installation of the outdoor unit (compressor) must be level, and the installer must use a spirit level to adjust it. The bracket for the outdoor unit should use the specified expansion bolts, and the correct number must be used. Be wary of workers skipping a few bolts for convenience, which could cause trouble later. If the distance between the outdoor and indoor units exceeds 3 meters, additional refrigerant pipes and drainage pipes must be carefully checked to ensure the added copper pipes and wires are of the same quality as the original ones.

When extending the refrigerant copper pipe, gas welding will be used to connect the extended copper pipe to the original one. Note: Request that the worker use silver solder and prohibit the use of copper solder! The extended refrigerant copper pipe must be tightly wrapped with foam plastic pipe and secured with plastic tape. There is also a technique in wrapping the refrigerant pipe, electrical wires, and drainage pipes with plastic tape; let the worker follow the standard operation process, otherwise, if not wrapped properly, rainwater may flow along the plastic tape into the house.

The ideal position for installing the outdoor unit is on the north or east wall, where there is less direct sunlight; if it must be installed on the south or west wall, shading measures must be taken without hindering air circulation. There should be no obstructions around the outdoor unit to maintain good heat dissipation. The side with the intake (wall side) and the side should be at least 20cm away from obstructions, and the front (outward exhaust side) should be at least 40cm away. The outdoor unit should be installed on a sturdy wall or balcony floor to reduce vibration. The unit should be as close as possible to the indoor unit to minimize pipe resistance and negative pressure loss. There should be no obstructions in front of the indoor unit to ensure the airflow reaches all parts of the room evenly.

The drainage pipe must be straight, slightly tilted outward to facilitate smooth water flow. If there are bends in the middle of the drainage pipe, it can easily cause water accumulation and poor drainage, leading to water overflow inside the indoor unit. If you need to move your air conditioner or determine whether a long-used air conditioner needs refilling with refrigerant, here are some simple methods:

1. Test: After the air conditioner has been running for half an hour, check if it can reach the set temperature (the air conditioner's cooling capacity should match the room size). Check if the operation light turns on and off intermittently (the compressor works like a refrigerator, turning on and off periodically). Otherwise, it indicates a lack of refrigerant.

2. Measure: Use a thermometer to measure the temperature difference between the air inlet and outlet of the indoor unit. A difference of over 10 degrees is considered normal. A well-performing air conditioner can have a difference of about 15 degrees. A small temperature difference indicates a lack of refrigerant.

3. Observe: After 15 minutes of operation, open the indoor unit panel and check if the evaporator is evenly covered with condensation. If only half is covered or there is frost/ice, it is abnormal.

4. Touch: If accessible (ensure safety), after 15 minutes of operation, touch the two valves of the outdoor unit. There should be a significant temperature difference. Frost on the fine pipe indicates a lack of refrigerant, while frost on the thick pipe suggests blocked system circulation.

5. Inspect: Use a pressure gauge to check the operating pressure of the air conditioner (not recommended for users due to safety concerns). Also, check if there is any greasy residue at the indoor joints and outdoor unit valves. If there is obvious grease, it indicates a leak because oil and refrigerant are mutually soluble; a refrigerant leak means an oil leak, and vice versa. Additionally, before refilling refrigerant after a period of time, check for leaks.

After the air conditioner is installed, ensure the installer checks for leaks at the connection points to prevent Freon leakage, which would significantly reduce the cooling effect. Prevent rainwater from flowing back indoors through the wall hole. During installation, a slightly higher indoor wall hole must be drilled. After installation, the gap in the wall hole must be sealed with putty. If using a drainage hole in the hallway, similar issues should be noted. Prevent indoor leaks. Ensure the condensation produced during cooling can be drained outside. When installing, pour a little water into the air conditioner's drip tray to check if it can drain outside. It's not fun if water floods your home. Prevent outdoor leaks. In winter heating mode, water may drip due to defrosting. Pay attention to ensuring the installer installs the water outlet and drainage pipe for the outdoor unit. Pay attention to the location of the outdoor unit. The outdoor unit of the air conditioner cannot be installed randomly; its location should facilitate future maintenance and care.

Why is the air conditioner installed with one high and one low?

I was also puzzled by this question, which someone else thought of. When my air conditioner was installed, it was like this: the indoor unit was mounted on the wall, and the outdoor fan was placed at the edge of the building, creating a height difference. Someone unintentionally came up with this question, wondering if it was simpler this way? It doesn't make much sense, right?! If there's no reason, just give a clear answer.

Hello, installing the indoor unit with one side higher than the other facilitates drainage! Typically, the drainage outlet side should be about 3mm lower than the other side! The indoor unit produces condensation! Installing the indoor unit parallel is also acceptable! There’s no real need for the outdoor unit to be installed with one side higher than the other! Unless the conditions for installing a Beijing Midea air conditioner do not allow it, it simply means it wasn’t installed properly! There’s no need for a height difference between the indoor and outdoor units! The height difference between the indoor and outdoor units of the air conditioner is regulated. As long as it’s within the range specified by Beijing Xinke Air Conditioning After-sales Service Hotline, it’s fine.

Can using air conditioning cause illness?

Frequent use of air conditioning can lead to illness.

Air conditioning sickness is an environmental factor-induced disease. With the increasing popularity of air conditioners in workplaces and homes, the incidence rate has been rising annually.

Cause: In summer, when temperatures are high and clothing is light, staying in a low-temperature environment for a long time transmits cold sensations to the body temperature regulation center, instructing the skin vessels to contract and the sweat glands to stop secreting to reduce heat dissipation and maintain body temperature; cold sensations excite the sympathetic nervous system, causing the abdominal cavity vessels to contract and weaken gastrointestinal movement, thereby producing various corresponding symptoms. Cold stimulation of a woman's body can affect ovarian function, causing ovulation disorders and menstrual irregularities. In addition to the aforementioned cold factors, tightly closed windows and doors, lack of fresh air; excessive temperature differences between the inside and outside of air-conditioned rooms; and although air conditioning filters can exclude most dust, they cannot exclude microorganisms, allowing pathogenic bacteria to easily reside and multiply in air-conditioned rooms—these are all causes of illness.
