Installation and testing of mobile air-conditioner MAC9010

Mobile air conditioning MAC9010 was acquired by the commercial chain at price from 250 leva ($156). The model is MAC9010, name "Home fit living". In on-line shops, I met the same model with the name Alaska MAC9010, which looks absolutely the same way.

Volume and temperature: The test is administered at the end of June in sunny day with a minimum clouds (t°21h=27°C). The room has a capacity of 42 cubic meters (3х4.30х3.25height). The measurement starts at 21 o'clock and continue for 2 hours. Originally the room temperature was 26°C and 59% of air humidity. Thermoregulator was calibrated to 24°C, and the slowest fan speed was set. Ten minutes after inclusion of the air conditioning system, the temperature decreased by 1 degree. Twenty minutes later reached 24°C. During the remaining hour and a half, the air conditioner only kept rated temperature, i.e. compressor worked periodically, and the fan was running continuously. Heat emiting sources in the room: one person and TV set present.

Air humidity and condensed water: My expectations were, that the air humidity would be decreasing significantly, because of the concentration of condensate in the AC container. After the initial decrease, at the end of the test has reached 55% which is almost as much as it's opening amount. In this case we do not admit dryness of the air, which in it's turn, does not contribute creation of static electricity (applicable for server rooms). 580ml water drained from the container.
  The air conditioner is set with 2 m plastic flexible goffer hose - diameter 14 cm. When used, it is expected that the collection of less condensate would present, compared with metal one. The use of tin cranks in air routes of drying plants, leads to a better removal of moisture. So, using of metal hose for the recirculation of exhaust air, should produce more condensate in the air conditioning system.
  In this particular case, an outbound air hose's material is of little importance, because of the minimum length (30cm), and the absence of a right angle turns.

Pressure in the room: The temperature of the air ventilated to the outside of the test room, was constantly 47°C. Insufflated air into the room during the operation of the compressor, was constantly 14°C. Woodwork is not air-tight and therefore does not create barriers to entry of air into the test room - i.e. not a depression.

Power consumption: Meter attached to the test set-up reported 1.6kW for two hours. I.e. the cost of the twenty-four-hour period would be 3.06 BGN:
0.8kW x 0.18lv x 16 hours= 2,30lv
0.8kW x 0.12lv x 8 hours = 0,76lv.

Consumption: While the compressor (work cooling), the disc on an electrical energy meter made 20 revolutions per 114 seconds. 1kWh = 1000W x 3600sec. On an electrical energy meter is specified that performs 600 revolutions per 1kWh.
So 3600000 x 20 / 600 = 120000Ws. These vat seconds divide to 114 seconds and we receive 1052W, which is the consumption (power) of the air conditioner.
Due to the fact that compressor works on a regular basis (turned on and off), the actual expenditure is accounted for by an electrical energy meter, pointed at the previous paragraph (0.8kW). Same method has been arrived at the power of the fan - 67W (at the slowest speed).

Use: Air from the conditioner is aimed at the neck of an adjacent room. When the door is opened, next room is also cooling, but without reaching low temperatures of the first room.

Disadvantage: Too noisy. Manufacturer's 68 dB, which in practice means that TV sound is choking down. Using of headphones instead is applicable.
