Doesn't air conditioning and refrigeration work in summer? Maybe there's something wrong here.

Although several days have passed in beginning of autumn, the hottest period of the year has not passed, and the high-temperature steaming and baking mode in summer continues to open. In such hot weather, it is time for the central air conditioner to stick to its post and fight the last battle of refrigeration. But many families will encounter this situation: even if the air conditioning temperature is set very low, the temperature will remain high.

What is the reason why air conditioning refrigeration is not in place?

In fact, there are many reasons why this air conditioner is not cold:

1. The filter is blocked.

2. Lack of R4 10 refrigerant.

3. The refrigeration effect of your outdoor unit is not good.

We installed a lot of air conditioners, and found that a large part of the after-sales problems were due to the strength of outdoor units, such as Hitachi Central Air Conditioning, in order to ensure the high quality of compressor performance, exhaust design and heat dissipation technology. After a series of functional experiments of outdoor unit in different scenes, it brings you a cool and comfortable living environment.

Simulate the installation environment with obstacles.

Due to the high density of urban space, the space left for outdoor air conditioners is not plentiful, and some outdoor air conditioners are in a sheltered installation environment, which easily leads to poor ventilation and affects the cooling and heating effect of air conditioners. In order to solve the limitation of outdoor installation environment and avoid poor ventilation, the static pressure of special outdoor unit for Hitachi central air conditioner can be adjusted at 30Pa, and it can be supplied by air duct in special environment, which can ensure that the air conditioning effect is not limited by space.

Simulate the exhaust distance of outdoor unit.

Some outdoor air conditioners have a short exhaust distance, which easily interferes with the air conditioners of neighbors and causes the problem of poor refrigeration. Hitachi Central Air Conditioning can achieve 6m long-distance air exhaust within the simulated outdoor air supply distance, which has better heat dissipation, will not interfere with adjacent air conditioners, can effectively avoid short circuit of return air, and achieve better cooling and heating effect.

Simulate quick start of outdoor unit

What is the first thing that comes to mind when you get home in the face of the high temperature outside? Of course, turn on the air conditioner and expect the oncoming coolness. However, if the air conditioner starts slowly, it will affect its cooling speed, and the original hot and dry mood will be more depressed. The compressor of Hitachi Central Air Conditioning can be started quickly after it is started, and the cooling effect can be achieved quickly without waiting for the cool breath.

Simulate outdoor high temperature environment

If the outdoor temperature is too high, some air-conditioning electrical boxes will reach 60℃ in high temperature environment, and enter the state of frequency-limited operation or shutdown protection, which cannot bring coolness to users. The outdoor unit of Hitachi Central Air Conditioning is not afraid of hot weather. The patented refrigerant heat dissipation technology can better cool the CPU area of the air conditioner, reduce the surface temperature of the frequency conversion module to about 35℃, ensure the normal operation of the air conditioner at the extreme high temperature of 52℃, and create a comfortable living environment.
