Description
Technical field]
The utility model relates to the field of air-conditioning and floor heating and electric control method thereof, especially relate to a kind of fan coil (indoor units) part and floor heating device is set and forms one, can comprehensively realize unitary air conditioner ground warming-up and the electric control method thereof of the multiple refrigeration of fan coil and floor, heat-production functions.
Background technology]
The steam compressing air conditioner facility have the adjusting aerial temperature and humidity function of refrigeration in summer, winter heating, under normal operation, electric energy from a unit of compressor end input, can obtain 1-4 cold doubly from the indoor heat exchanger end, can also obtain 2-5 heat doubly from the outdoor heat exchanger end simultaneously, obtain in such a way heat if we adopt, its heating efficiency is 2-5 times of direct Electric heating.According to law of conservation of energy: the heat dissipation capacity of the refrigerating capacity of the electric energy+air conditioner of extraneous input air conditioner (heat that indoor heat exchanger absorbs)=outdoor heat exchanger of air conditioner accordingly, produces high efficiency heat pump type air conditioner.
The fan-coil heating of conventional heat pump formula air conditioner, the general refrigerant that adopts is become the condensation heat release of liquid by gas, then by indoor fan, heat directly is thrown into room air, but according to the air principle of expanding with heat and contracting with cold, the higher hot-air of temperature is to rising, and the cold air that temperature is lower sinks.So interior space heat skewness during traditional fan-coil heating, namely heat concentrates on head and above upper zone thereof relatively, allow the people feel the upper heat of head, but underfooting or ice-cold feels very uncomfortable.In addition, use fan-coil heating, if reach 22～25 ℃ of indoor environment temperatures, in refrigeration system, the condensation temperature of refrigerant generally will be over 54 ℃, condensing pressure is large, the unit start-stop is frequent, and the machine startup electric current is large (can meet or exceed normal 5 times) very, causes the machine energy saving relatively poor.
And floor heating is to bury the heating pipe under the floor underground, if reach the indoor environment temperature of 22～25 ℃, in refrigeration system, the condensation temperature of refrigerant can be down to approximately 45 ℃, aqueous medium (perhaps other larger liquid mediums of thermal capacity) reaches 38 ℃～40 ℃ in water fluorine heat exchanger with after the refrigerant heat exchange, then flows into to be embedded in and underfloorly adopt heat pipe and heat exchange is carried out on the floor.Because the required condensation temperature of floor heating is lower than the condensation temperature of conventional fan coil pipe heating, its efficiency is higher.Simultaneously, floor heating is to utilize the heat radiation on floor and the principle that hot gas rises, and realizes the room heating.And the room is first to begin to warm up from the floor, allow the people feel to be " warm give birth to from sole ", and the amount of stored heat in the rooms such as floor, body of wall is large, and floor heating is highly stable, is difficult for fluctuation, so comfort level is very high.
But traditional floor heating generally adopts the heat supply of central air-conditioning mode, and it involves great expense, and cost is higher, and a lot of people hold and dare not accept.In addition, the tradition floor heating aqueous medium (perhaps other larger liquid mediums of thermal capacity) generally by outdoor host computer through the refrigerant condensing heat-exchange, heat up into hot water and input again the indoor underfloor heating pipe that is embedded in, water route connected system quantities between its outdoor host computer and indoor units is large, installs complicated.And, adopt heat pipe and be embedded under the floor, just in case detect when breaking down and maintenance load large, length consuming time, the maintenance period is not easy to find desirable standby heating scheme.
And, although the high degree of comfort that traditional floor heating has aforementioned " warm living from sole " can not start heating fast, just can reach comfortable heating requirement after winter, new start was even wanted a couple of days, just gone home the heating demand when larger the user especially, can not increase fast the heating amount.So floor heating generally keeps 24 hours normal open states, even also not exclusively close unit (still operating in the lower temperature standard) daytime during the family unmanned state.And, if the insulations such as room exterior wall, window-glass are relatively poor or doors and windows sealing is poor, even also may exist heat to a certain degree to lose waste when floor heating is stayed at home the unmanned state.
