The outdoor unit controls the outdoor fan based upon the operation signal sent from the indoor unit, and also controls revolution speed of the compressor motor.

The power coupler (IC20) for 4-way valve is turned on, and turned off in defrost operation.

(1)Heating capacity control

Calculate the difference between temperature detected by room temp. sensor every minute and the set temp. set on “Temp. indicator” and variation amount of room temp.

Then, obtain the correction amount of the com- mand signal, and correct the current frequency command signal.

(2)High-temp. release control

If temperature of the indoor heat exchanger

detected by the indoor heat exchanger sensor is 55° C or higher, compressor motor speed is gradually lowered to prevent over-temp. rising of

compressed pressure.

If temperature becomes below 48° C, return to above item (1).

(3)Current release control

The input current of compressor and outdoor fan motor (Precisely inverter main circuit control section) which occupies most of air conditioner input is detected by the outdoor current sensor. The compressor motor speed is lowered gradually according to the range of TO (outside air temp.) if the input current exceeds the current value determined in each zone as shown in Fig. 8-2-8 so that the input current does not exceed the set value.

In case that the current lowered by approx. 0.5A than each set value, return to above item (1).

(4)Defrost control

1)Detection of frost

In heating operation, time duration while the compressor operates is counted, and defrost operation starts by any condition described below.

a.The counted time is 28 minutes or more, and status that temperature of the outdoor

heat exchanger detected by the outdoor heat exchanger is –20°C or lower continued for 2 minutes or more.

b.The counted time is 28 minutes or more, and status that temperature of the outdoor

heat exchanger detected by the outdoor heat exchanger is –7°C or lower and temperature lowered by 2.5° C than the minimum value of the outdoor heat exchanger during 10 to 15 minutes count time continued for 2 minutes or more.

c.The counted time is 34 minutes or more, and status that temperature of the outdoor

heat exchanger detected by the outdoor heat exchanger is -5°C or lower and temperature lowered by 3.0° C than the minimum value of the outdoor heat exchanger during 10 to 15 minutes count time continued for 2 minutes or more.

d.If the following three conditions are satis-

fied, defrost operation (Timer defrost) starts after heating operation for 37 minutes.

RAS-13UAV-E2, RAS-13UKV-E2 specifications

The Toshiba RAS-13UKV-E2 and RAS-13UAV-E2 air conditioning units represent a significant step forward in both comfort and energy efficiency. Designed for residential and light commercial use, these models are packed with features that cater to diverse climate control needs while adhering to modern standards of sustainability.

One of the standout features of both models is the implementation of inverter technology. This advanced system allows for more precise temperature control by adjusting the compressor speed based on the ambient temperature requirements. This not only enhances energy efficiency but also ensures a quieter operation compared to traditional air conditioning systems. As a result, users benefit from consistent comfort without the disruptive sounds often associated with cooling units.

The RAS-13UKV-E2 and RAS-13UAV-E2 also feature a high energy efficiency rating, which is crucial for reducing electricity bills. The Seasonal Energy Efficiency Ratio (SEER) is a vital measure of energy efficiency over an entire cooling season. Both units excel in this regard, making them an environmentally friendly choice. This is further supported by Toshiba's commitment to incorporating R32 refrigerant, known for its lower environmental impact compared to older refrigerants.

User convenience is enhanced with integrated smart controls. Both models are compatible with wireless remote control features, allowing for easy adjustments from a distance. This is complemented by programmable settings that let users schedule operation times, ensuring that the units run only when needed, which further optimizes energy consumption.

Design-wise, these air conditioners boast a sleek and modern appearance, making them a visually appealing addition to any room. They are constructed with durable materials that ensure longevity and reliability. Moreover, the filters are designed for easy maintenance, ensuring cleaner indoor air quality and prolonging the lifespan of the unit.

The Toshiba RAS-13UKV-E2 and RAS-13UAV-E2 units also come equipped with advanced air purification technologies. These features help to reduce airborne pollutants and allergens, contributing to a healthier indoor environment. With exceptional cooling and heating capabilities, easy installation, and advanced features, these models are designed to meet the modern user's needs for comfort, efficiency, and health. Overall, they represent an excellent investment in both cooling technology and eco-friendly practices.
