Defrost Control | Haier R410A guide

Operation Details

■Healthy Dehumidification Mode

•When the dehumidification operation input by the remote controller is received, the intake air temperature is detected and the setting temp is automatically set according to the intake air temperature.

26°C ≤ Intake Air Temp => 25°C

24°C ≤ Intake Air Temp < 26°C => Intake Air Temp-1°C 18°C ≤ Intake Air Temp < 24°C => Intake Air Temp-0.5°C

Intake Air Temp < 18°C

=> 18°C

•While in compressor off, the indoor fan repeats low airflow speed and pause.

•While the intake air temp is between compressor on temp. and compressor off temp., 10-min dehumidification operation and 4-min compressor off repeat

Compressor ON Temp. => Setting Temp+0.5°C Compressor OFF Temp. => Setting Temp-0.5°C

•In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.

■Heating Mode Operation

•When the intake air Temp. reaches Compressor OFF Temp., the compressor is turned off. When the intake air Temp. reaches Compressor ON Temp., the compressor is turned on.

Themo ON Temp. => Setting Temp. +2˚C Themo OFF Temp. => Setting Temp.+4°C

•While in compressor on, when above 38°C, it operates with setting airflow speed (while in sleep mode, with the medium airflow speed).

•While in compressor off, the indoor fan is off when the indoor pipe temp is below 33°C , when above 35°C , it operates with the low airflow speed.

•While in defrost control, both of the indoor and outdoor fans are turned off.

■Defrost Control

•While in heating mode operation in order to protect outdoor unit from freezing, reversed to cooling cycle to defrost of the outdoor unit.

■Fuzzy Operation (Outdoor unit C/O Model)

•According to the temperature set by Fuzzy rule, when the intake air temp is 0.5°C or more below the setting temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is turned on.

Compressor ON Temp => Setting Temp+0.5°C Compressor OFF Temp => Setting Temp+0.5°C

•At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the intake air temp at that time.

26°C ≤ Intake Air Temp => 25°C

24°C ≤ Intake Air Temp<26°C => Intake Air Temp+1°C 22°C ≤ Intake Air Temp<24°C => Intake Air Temp+0.5°C 18°C ≤ Intake Air Temp<22°C => Intake Air Temp

Intake Air Temp<18°C

=> 18°C

•When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the Fuzzy key value and the intake air temperature at that time are compared to select the setting temperature automatically according to the Fuzzy rule.

•While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the temper- ature

R410A specifications

Haier R410A is a refrigerant that has gained significant attention in the HVAC industry due to its environmental benefits and efficient performance. As a hydrofluorocarbon (HFC) refrigerant, R410A is designed to replace the older R22 refrigerant, addressing environmental concerns and aligning with global initiatives to phase out ozone-depleting substances.

One of the primary features of Haier R410A is its low environmental impact. R410A has a significantly lower ozone depletion potential (ODP) compared to R22, making it a more environmentally friendly option. Additionally, it has a global warming potential (GWP) that, while still higher than natural refrigerants, is considered acceptable in terms of modern refrigerant usage and regulatory compliance.

The performance characteristics of R410A are another key point of interest. This refrigerant operates at higher pressure levels compared to R22, which allows for improved heat transfer efficiency. This results in enhanced cooling and heating capabilities, enabling HVAC systems designed for R410A to deliver superior performance in various climate conditions. The higher efficiency translates to lower energy consumption, meaning users can enjoy a comfortable indoor climate while keeping energy bills in check.

In terms of technology, Haier has integrated R410A into a range of air conditioning and refrigeration systems, showcasing the refrigerant’s compatibility with modern HVAC designs. Many of Haier’s products feature advanced inverter technology, which optimizes energy use by adjusting the compressor speed according to the cooling demand. This not only improves efficiency but also extends the lifespan of the equipment.

Moreover, Haier R410A systems are often equipped with smart technologies such as Wi-Fi connectivity and intelligent control features. These innovations allow users to monitor and control their HVAC systems remotely, promoting user convenience and energy savings.

Safety is another characteristic of R410A systems. Although R410A is non-toxic and has a very low flammability risk, it requires appropriate handling procedures due to its higher pressure. Haier adheres to rigorous safety standards in the design and manufacturing of its HVAC units, ensuring that end-users can operate their systems with peace of mind.

Overall, Haier R410A refrigerants represent a significant step forward in achieving efficient, environmentally responsible heating and cooling solutions. With their advanced technology, excellent performance, and commitment to safety, Haier's R410A systems have become a preferred choice among consumers looking for reliable HVAC solutions that also consider ecological impact.
