Description
Technical field
It the utility model is related to the mobile reciprocation type heat pump defrosting system using compressed air, and in particular to empty using compression
Gas, which mixes with anti-icing fluid two and controls nozzle to move back and forth up and down by motor and belt, to be sprayed except air source heat pump system
System evaporator surface frosting.
Background technology
It is " 13 " state key project financing that coal, which changes clean resources project, and is beginning to promote many years ago.After 2013
More increase propulsion dynamics.Rural area pilot since 2013, pilot is carried out on Beijing, Hebei and other places first, is promoted, it is modern
After will the north carry out promotion and implementation more on a large scale.Winter is China's atmosphere pollution more serious period, wherein, it is coal-fired
It is one of the main reason for causing air pollution with vehicle exhaust.The coal-smoke pollution feature of northern China is obvious, due to heating
Coal contaminants discharge capacity increase severely, winter or weeds, rubbish and crop straw burning season occurred frequently, plus it is dry grade nature because
Element, winter heavily contaminated weather concentrate occurred frequently, haze exacerbation.According to particulate matter source resolution result, it is coal-fired to Tianjin winter PM10,
PM2.5 genes’ contamination ratios are respectively 42.3%, 43.3%, are 2.2 times, 2.3 times of other season average levels respectively.
Air source heat pump heating, it is a kind of environmental protection, the heating system of energy-conservation.Low-temperature heat quantity in its main absorption air comes
Hot water preparing, and by fan coil, exclusively warming-up or laying floor heating layer, active radiating, snugness is provided for family
Environment.Without burning, no waste gas and wastes discharge, the threat of discharge and the gas poisoning of coal ash, cleaning, environmental protection are eliminated.Its water
Electricity is completely separated, non-contact electric, electric leakage potential safety hazard, and energy consumption is low, consumption 1kW electric energy, absorbs 3kW air energy, can produce
4kW heat energy, than purely by the electric heating energy-conservation 75% of electric energy heating.It can realize Automated condtrol, can adjust Indoor Temperature,
Humidity, humiture are constant comfortable.Therefore, it is a kind of energy-conservation behave, and the ground such as Beijing, Tianjin well to promote air source heat pump
Have begun to promote the use of on a large scale.But air source heat pump generally existing frost.Evaporator temperature is less than surrounding air
Dew-point temperature when, fin surface can produce condensation water on whole evaporator, when ambient air temperature is less than 0 DEG C, condensation water
Bao Shuan will be condensed into.Frosting can influence machine heating effect when serious.General heat pump product has automatic defrosting function, it is ensured that
Unit normal operation.The defrost technology used at present mainly has three kinds：The reverse defrost of four-way valve, hot-gas bypass defrost and electrical heating
Defrost.Three kinds of methods cut both ways.For the reverse defrost of four-way valve during reverse cycle defrosting, outdoor evaporator is changed into condenser,
Indoor condenser is changed into evaporator.Unit takes heat to melt frost layer from indoor environment, causes the deterioration of indoor environment.The opposing party
Face, in order to prevent to blows cold wind indoors, indoor fan is closed during defrosting, defrosting energy be mainly derived from compressor work and
Indoor heat exchanger coil pipe accumulation of heat.Therefore the deficiency of defrosting energy is caused, so as to cause relatively low pressure of inspiration(Pi), longer defrosting
Time, relatively low indoor environment temperature.Hot-gas bypass defrost is exactly that compressor air-discharging switches to outdoor fin-tube type by magnetic valve
Carry out defrost in the pipeline of evaporator.Its biggest advantage is that simple system.Shortcoming is due to no external heat source, and its heat is whole
The heat that the motor operating of some energy and compressor in itself before compressor shutdown is sent.The heat is limited.When
Running into environment temperature reduces and when frosting is thicker, has the defects of defrost is not net, and defrosting time is long can cause compressor liquid
Hit phenomenon.The actual defrost effect of electrical heating defrost is ideal, but needs to use electric heating tube using electrical heating defrost, and this makes
The energy consumption increase of air source heat pump is obtained, and then its advantage saved has not been existed.In addition, the service life of electric heating tube has
Limit, and cause possibility on fire in the presence of overheat, also there is hidden danger in terms of security.
