Q:What is the whole heat exchange fresh air ventilator?
Depends on the main control panel is not cold and warm, single cold common motherboard. Only a generic motherboard can be changed. In the single cold air-conditioning on the outdoor machine to install the appropriate specifications of the four-way valve, adjust the amount of refrigerant to the appropriate level can be.
Q:Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter
Can be small, according to your roof to do what material.
Q:External wall insulation method of operation There are several combinations of materials
30-150 per square meter has, mainly to see the material, thickness and so on
Q:Air conditioning ventilation when the sound is a big reason
According to my specific circumstances, in the following seven major hazards include the division, sub-project focus on control
Q:HVAC Heating: What are the main components of the air distribution system?
The reasons are the following: 1. Household electricity is not enough, can not start the compressor, so in the heating state can only be ventilated state, cooling the state directly jump electricity; 2. See if you are reported failure, Code to determine the need for on-site inspection in order to know the specific situation; 3. Four-way valve should be no problem, do not just believe that this is the problem Oh; help your words to adopt
Q:Public building design, the building structure and water is generally designed by the Architectural Design Institute, air conditioning and ventilation is based on the design of the interior? Or first air conditioning ventilation?
Normal heat absorption is also due to poor ventilation (dirty) and air humidity so icing
Q:Air conditioning machine work when the sound is too much reason
Color steel plate, refers to the color coated steel plate, color coated steel plate is a kind of organic coating with steel plate
Q:Air to water heater host and air conditioning host is not the same
This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.
Q:The United States direct mail dyson hp01 Dyson air purification cooling machine triple in the country to warranty it
Embedded stove, such as the use of rubber tube connection, then the rubber tube in the platen, often subject to heat radiation easily aging; and aging, falling more difficult to find, so many local poisoning and other vicious accidents
Q:Single cold air conditioning function can not change the cold and warm?
Air conditioning heating than the cooling power consumption, power consumption and ambient temperature and set the temperature has a great relationship, the general cooling 1 hour 1-2 degrees, heating if the auxiliary heating about 2-3 degrees. If you want to save the appropriate temperature can be set higher, the general and the ambient temperature difference of about 5 degrees people feel more comfortable, shut off undesirable, not reach the purpose of saving.
