Q:A set of house, indoor area of 90 - the sitting room, about 30 + restaurant - 33 - should buy how much energy consumption of air conditioning can be the most appropriate, effect also right?

Considering the number and the change of heat release, it is recommended that the selection of 6000 ~ 7200, cabinet air conditioning blowing direction: toward the dining area. Such as economic ability allow, can buy a ark of frequency conversion between 6000 ~ 7000.

Q:Can adjust indoor air conditioning circulation within the outer loop

With changing behavior of household air conditioner, just have the function of the outer loop. Circulate in general family expenses air conditioning only, and not the function of the outer loop. But in air with function of air conditioner, can introduce outdoor fresh air into the indoor, can have the function of the outer loop. Air conditioning units are usually used in confined space, long time, can make indoor air pollution, even no collateral in fresh air function of air conditioner, air conditioning after a period of time, it is best to open a window ventilated 5 ~ 10 minutes, to ensure the indoor air clean.

Q:Recently to do some engineering of hvac engineering, they want to install VRV aircon on the first floor, central air conditioning in the second and third floor, I don't understand, these two kinds of air conditioning is not the same? Had heard that VRV aircon is the central air conditioning! The whole central air conditioning is not good?

VRV central air-conditioning outdoor host by of outdoor heat exchanger, compressor and other refrigeration accessories, terminal device is composed of direct evaporative heat exchanger and fan indoor machine. An outdoor several indoor machine via the line can handle liquid refrigerant. 58 air conditioning there are many companies that sell VRV central air-conditioning, such as shandong, rhett, there are still many dealers, daikin, gree, midea have do VRV unit.

Q:Household air-conditioning outlet temperature is normal?

The outlet temperature of air conditioning is not according to the number of horse generalisations. Air conditioning running 15 minutes later with a thermometer to measure: 1, refrigeration, air inlet temperature minus the outlet temperature should be greater than 8 degrees. 2, heating, air inlet temperature minus the outlet temperature should be greater than 16 degrees. In the temperature range, air conditioners are normal operation. Air-conditioning outlet temperature related to the following conditions: whether indoor temperature, outdoor temperature, electric heating, indoor fan air volume, air conditioning to the size of the old and new, and whether the power size, air conditioning refrigerant. Usually, air-conditioning outlet temperature without a fixed value, it should be said that no less than 8 degrees outlet and inlet temperature of the temperature difference is normal. Users can in the open air conditioning, the outlet and inlet respectively using a thermometer to measure temperature, if there are 8 degrees temperature, air conditioning is normal (typically has 11 to 13 degrees temperature difference). Air-conditioning outlet temperature is according to the machine speed and to measure the position of changing, general into the outlet temperature difference for the 14 degrees above the normal (general electric auxiliary heating mode to open hot outlet temperature around 40 degrees).

Q:Air conditioning is very demanding?

Yes, the power consumption of air conditioning is very big, especially in the winter heating work is more demanding, in order to save electricity, one is to buy air conditioning can effect comparing high, can effect comparing the highest power level

Q:How many degrees electric air conditioning in a day

Air conditioning how much electricity consumption, it doesn't matter how many temperature with you, no matter how much you open the temperature, the compressor, the normal work of the motor are all the same, the power consumption. Your is 1.5. Generally is 35 machine, is the capacity is 3500 w. Refrigerating capacity, it is said the capacity of air conditioning refrigeration (professional view should call BTU, because users don't understand what is BTU, so KongDiaoJie deliberately converted to W), not on behalf of the power, not the power consumption. Real power is not set in stone. You can see, each air conditioner has an energy efficiency label (around is blue, the middle one is white), one can effect comparing above, can effect comparing value = refrigerating capacity/actual power consumption (i.e., the input power). All your actual power consumption = refrigerating capacity/eer value, you can draw your actual power consumption is how much watts (that is, the power input number) above. Every 1000 w is a kilowatt-hour. Can you tell me, you can effect comparing so I will calculate for you, but generally 35 machine, press can effect comparing is level 5 to calculate words, generally about 1000 watts. About an hour once is electricity. So basically is to see your own how much is the air conditioning can effect comparing.

Q:How to add refrigerant home air conditioning

Boot refrigeration mode, even from outside the machine stop valve on the refrigerant cans, they added

Q:Useful three-phase electric air conditioning is what kind of?

Three-phase air-conditioning outside machine is electric heating and air conditioning compressor is 380 v voltage. To apply to the local power supply bureau, general installation meters must be replaced three phase meters. Need to choose according to use all electric appliance total power meters, choosing a meter power supply bureau will specify what to use electric meter. Socket is four holes, respectively is: A, B, C, PE (grounding protection). If A, B, C three-phase imbalance, N line at this moment, otherwise due to the zero line current exist, can produce A potential difference, endangering the personal safety

Q:Household air conditioner 5 horses, whether need to change electricity

In-laws if is 50 flat with 3 p machine is good, need not 5 p, generally 5 p can drive 100 machines, with less than. If you want to use 5 p machines, kiss'd better ask the shop assistant, because only he knows his machine, the most different brand different models of machine some electricity is not the same

Q:Air conditioning general under the condition of high and low pressure is normal?

Static pressure associated with outside air temperature, the higher the temperature, the higher the static pressure of refrigerant, if the air temperature is above 30 degrees, static pressure will reach 1 million mpa. Summer: Runtime of high pressure up to 2 million mpa in the summer, but is not greater than 2.5 million mpa. Under low pressure in normal circumstances in 0.5 million (refers to the environmental temperature 30 degrees)! Summer is the highest temperature will reach 0.6 million mpa, more than may influence the refrigerating capacity of the air conditioning! Winter: High pressure could reach 2.5 million mpa (for heating) Low voltage depends on the environment temperature, generally at about 0200000 mpa
