Description

Energy-conservation cold-heat air-conditioning, water-heating three-purpose machine of a kind of four seasons
Technical field:
The present invention relates to the power-saving technology of a kind of air conditioner and water heater.
Background technology:
Existing air conditioner is only useful in two seasons of winter in summer, and spring, autumn, this seasonal product overstock the extensive fund of producer and businessman generally by idle, and the equipment that the user purchases yet utilization rate is not high, is a kind of waste of equipment and fund.The heat that existing air-conditioner discharges to outdoor environment when freezing summer is about 3 times of cooler compressor power consumption, is again wasting of a kind of heat.Domestic, electric water heater power consumption is big, and electric energy quality utilization rate is low, and the electric heating transformation ratio is less than 1, and all will use throughout the year, and three-person household is heated to 50 ℃ with warm washing water's 120 kg from 20 ℃ and calculates, about 4.2 degree of day power consumption, about 1500 degree of year power consumption.Therefore, improving air-conditioner utilization rate and the energy-conservation of water heater has been current household electric appliances and energy-conservation significant research topic.By retrieval, have based on the utility model with this principle of energy savings at present to comprise that the patent No. is 15 of 85202970,90201632,90217674,93206750.6,94216590,94237059,95222060,95237765,95228722 utility models, patent of invention has binomial: 90109269.X " be used to regulate the method for air and supplying hot/cold water " and 92110270.4, " refrigerating heat pump hot water apparatus ".The mode that above patent adopted roughly can be summed up as two classes: a class is air-cooled condenser to be used instead water-cooled condenser substitute, and no longer keeps air-cooled refrigerating function; Another kind of is to increase water-cooled condenser before the air-cooled condenser inlet with after the exhaust outlet of compressor.Last class scheme is fit to do Teat pump boiler, but function singleness, because of summer very big with air conditioning quantity, the water yield that water-cooled condenser need consume is also very big, only depends on the domestic consumption can't balance, and is with causing the waste of big water gaging, inadvisable in the city of lack of water; Though back one class scheme can be taken into account room air cooling and supply domestic water in summer, produces hot water in spring, autumn, three seasons inconvenience in winter, can not bring into play the Teat pump boiler effect of air-conditioner throughout the year.
The patent No. be 97227264.X's " energy-saving air conditioner drags water heater " propose in the cooling and heating air conditioner loop, to set up two-position four-way valve and two two position three-way valves with five air chambers, make device carry out the function of refrigeration gas, hot gas, hot water respectively separately.Though this device can obtain hot water throughout the year, can not when refrigeration gas, obtain hot water simultaneously; The patent No. is " the changes in temperature room air conditioner of hot water can be provided " of 95246577.9, belongs to air-cooled condenser and connects the hot water type before.
The patent No. is a kind of idle call refrigeration/thermal storage heat/hot system that adopts reverse-flow subcooler of 961212217, provides a kind of and has made the cold-producing medium that flows out from condenser in the kind of refrigeration cycle cross method cold and the raising refrigerating capacity by cold-storage water.But this patent does not relate to the problem with the water heater logotype.
The inventor's the patent No. be 00264455.X's " a kind of energy saving tripurpose machine for hot and cold air conditioning and supplying hot water " introduced the three-way set that adopts a two way solenoid valve and double capillary double check valve throttle mechanism, though realized both having kept existing air conditioner repertoire substantially, again can be in the imagination of four seasons energy-saving heat-production water, but owing to only used a gas circuit two way solenoid valve and double capillary throttle mechanism design side by side in the loop, three-way set can be collaborated in obsolete air cooling heat exchanger under this mode at the starting phase cold-producing medium of only doing the Teat pump boiler time spent, cause closed circuit refrigerant amount instability and condensation of refrigerant Waste Heat Recovery incomplete, in addition, use at present commercially available two-way electromagnetic valve as the cold-producing medium gas circuit control time spent, deliver variation with the valve body gap because of swell increment is different at high pressure-temperature state operating mode bottom spool, be prone to mechanical breakdown.
Summary of the invention:
The objective of the invention is in order to overcome the deficiency of existing air-conditioner and water heater, and the imperfection of foregoing invention and utility model, by to existing air conditioner and water heater refrigerant circulation loop, throttle mechanism, the improvement of gas circuit reversal valve and water cooling heat exchanger, a kind of more high efficiency that has is proposed, reliable, easy for installation and help the energy-conservation cold-heat air-conditioning, water-heating three-purpose machine of the four seasons that reduces manufacturing cost, its the double water that heats of gas that not only can freeze in summer, and also can make the usefulness of independent heat pump type water heater in three seasons of winter in spring and autumn, more energy-conservation 100% than electric heater summer, three seasons of winter in spring and autumn can 70%.
