Q:Geothermal coil spacing is too hot not how to do
Home improvement 200. works 350...
Q:To warm the warranty period from when to count
First, to warm the warranty period is generally the beginning of the check if the developer is to do the warmth of the warranty period for the two heating period. Second, the "home quality guarantee" warranty period from the developer will be completed acceptance of the use of housing from the date of calculation. Third, the specific quality of the warranty period and the warranty period is: the foundation and the main structure within a reasonable life life; roof waterproof for 3 years; wall, kitchen and toilet ground for 1 year; general agreement basement and pipeline leakage For 1 year; wall, ceiling plaster layer off for 1 year; ground empty drum cracking, large area sand for 1 year; doors and windows cracked, hardware and sanitary ware damaged for 1 year; lamps, electrical switch damage to 6 Month; pipe block for 2 months; heating and cooling system equipment for the two heating period or the heating period; other parts, parts of the warranty period, agreed by the buyers and sellers, and written in the project quality assurance.
Q:What are the common parts of the car heating and cooling system?
Radiator, fan, outlet is a common part.
Q:Discusses the working principle of home split air conditioning and draws the schematic diagram
I've learned that my book is there. I also have annotations to explain.
Q:What is the difference between the quality of the new generation of red tube and the original?
Plus color mother
Q:Home coal-fired heating stove and electric heating furnace which is good
Coal, cheap to save money. Electricity, clean and easy to control, expensive
Q:Rooftop electric film from the heating how?
In the early years, many of the time to do so, but the effect is not good, are now doing on the ground.
Q:To warm the winter can not live without water can be frozen to warm it?
Too cold, if the indoor temperature below 5 ℃ will crack. If you do not need to do some maintenance. Maintenance methods: 1, the winter should not pay attention to heating, watertight parts should be prevented from cracking and heating pipe in the water clogging the pipeline. 2, not to be activated when the watertight parts to prevent cracking, the system is not installed after the winter that year, such as indoor temperature below 5 ℃, the system should be all the air with air compressor blowing, to prevent the system by freezing. Winter should not be enabled when the geothermal heating system should pay attention to protection, to prevent the water diversion components or heating pipe in the water icing.
Q:What is the working principle of air source heat pump and what is it?
Air source heat pump: air energy (source) heat pump, as a heat pump technology, a "natural energy porters" reputation, with the use of low cost, easy operation, heating effect is good, safe, clean and other multiple advantages. The energy in the ubiquitous air as the main driving force, through a small amount of energy to drive the compressor operation, to achieve energy transfer, without complex configuration, expensive water, recharge or soil heat transfer system and dedicated room, to gradually reduce the traditional Heating to the atmospheric environment to bring a large number of pollutant emissions, to ensure the effectiveness of heating while taking into account the purpose of energy conservation and environmental protection. The air source (source) heat pump is driven by the motor. Working principle: Steam compression refrigeration cycle Operating principle, the ambient air is cold (hot) source to produce cold (hot) wind or cold (hot) water equipment, the main zero Components include hot side change equipment, heat source side heat exchanger equipment and compressors. The air energy source heat pump uses the heat in the air as a low temperature heat source, through the traditional air conditioner in the condenser or evaporator for heat exchange, and then through the circulatory system, extraction or release of heat, the use of unit circulation system to transfer energy to the building To meet the needs of users on the hot water, to warm or air conditioning. Air source heat pump technology is based on the inverse Carnot cycle principle to establish a kind of energy saving, environmental heating technology. Air source heat pump system through the natural energy (air heat storage) to obtain low-temperature heat source, the system after the integration of high-temperature heat collector, used to take (for) warm or supply of hot water, the whole system heat collection efficiency is very high.
Q:Maintenance of gas boiler
I'll help you answer. 1, your home has been using the boiler, not off this will not have any problems. 2, radiator pipe is not leaking, but the pipeline pressure drop, it may be other parts of the system there are problems, otherwise the pressure will not be separated by three poor decline. Under normal circumstances, to maintain the wall pressure on the top of the pressure display is 1-1.5bar, below this pressure to pay water pressure. The pressure to your home often decline, they can not find the reason, I suggest you find a boiler after the sale to see you, the problem in time to solve.
