Abstract
The utility model relates to an air-source heat pump hot-water device provided with a novel-style throttling device, which substantially comprises a compressor, a condenser, a throttling device, an evaporator, a water pump, a draught fan, a power source, a thermorelay, and a contactor or the like. The condenser drives water flow to take away heat through pipes by the water pump, the evaporator can exchange heat with outdoor air driven by the draught fan, the throttling device comprises parallel double capillaries, wherein a circuit of one of the parallel double capillaries is provided with a solenoid valve. When the outdoor temperature is above a certain set point, the solenoid valve is opened under the working of the thermorelay, the throttling device comprises parallel double capillaries, when the outdoor temperature is below a certain set point, the solenoid valve is closed, the throttling device comprises a single capillary, thereby the throttling device can be safely and stably operated both in winter and in summer, and adapt to the working condition of compressor. The utility model can solve the shortage problem of low-power expansion valve at present market, and has the advantage of simplicity, stability and low-price.
Description
Technical field
The utility model relates to a kind of air-source heat pump hot water with novel throttling device, belongs to using energy source and technical field of heat pumps.
Background technology
The small air source heat pump hot water mainly is made up of compressor, condenser, throttling arrangement and evaporimeter, with advantages such as its energy-conserving and environment-protective on market by as haircut, food and drink etc. in a large number the petty trade users be badly in need of, be that it is workable for the small-sized heat pump machine of main thermal source with air.But, atmosphere at all seasons in variations in temperature very big, thereby evaporating temperature and pressure alters a great deal, also therefore in the circulation of electric power compression heating power the pressure of throttling arrangement will alter a great deal.Adopt heating power expansion valve to can be used as its throttling arrangement, but it is few to join the heating power expansion valve product of minicomputer.Do not solve this technical problem, just be difficult to make this class unit under annual weather, to be used.Before this, the someone adopts the throttling arrangement of double capillary, dual-coil electromagnetic valve, utilizes magnetic valve that it is switched in summer in winter, but magnetic valve price height, easy break-down should be used as far as possible less.
Summary of the invention
The utility model provides a kind of throttling arrangement of double capillary list solenoid valve type of particular design, addresses the above problem, and not only simply but also economical, reliability was also big.
The technical solution of the utility model is as follows:
Air-source heat pump hot water with novel throttling device, mainly water pump pipeline, evaporimeter and the vaporizer side that is used for heat exchange by compressor, condenser and condenser side is used for blower fan, throttling arrangement and the power supply of heat exchange and temperature relay etc. and forms.
Throttling arrangement is made up of the capillary of two parallel connections, and one of them installs a normally closed solenoid valve additional, and magnetic valve is connected with temperature relay, contactor, power supply etc.When outdoor temperature was higher than certain setting value, magnetic valve was opened under the effect of temperature relay, and throttling arrangement is made of the double capillary of parallel connection; Otherwise, when outdoor temperature is lower than certain setting value, closed electromagnetic valve, throttling arrangement is made of single capillary.Like this, throttling arrangement of the present utility model can adapt to the needs of the big pressure reduction between condenser and the evaporimeter at cold day, in hot day, because double capillary flow resistance in parallel reduces, can adapt between condenser and the evaporimeter needs than small pressure difference.
The utility model and double capillary dual-coil electromagnetic valve have relatively reduced by a magnetic valve, have increased reliability, economy.
Description of drawings
The structural representation of the air-source heat pump hot water of the double capillary list magnetic valve throttling arrangement that Fig. 1 provides for the utility model.
Each unit number and title are as follows among Fig. 1:
The specific embodiment
Below in conjunction with accompanying drawing the concrete structure of the present utility model and the course of work are further described.
As shown in Figure 1, this air-source heat pump hot water mainly comprise compressor 1, condenser 2, and condenser side be used for heat exchange water pump 5, water inlet pipe 7, outlet pipe 8, throttling arrangement assembly (being capillary 3a, capillary 3b, magnetic valve 3c), evaporimeter 4 and vaporizer side and be used for the blower fan 6 of heat exchange and the temperature relay 11 that is connected with 3c and power supply 9, contactor 10.Connect into loop with pipeline between described 1,2,3,4, fill in the loop with cold-producing medium (to call working medium in the following text).
The course of work of the present utility model is as follows: connect power supply, after charging into water from cold water pipe 7 by water pump 5 pressurization in the condenser 2, compressor 1 and vaporizer side are used for the blower fan running of heat exchange, gaseous working medium boil down to high temperature and high pressure gas is entered condenser 2, enter the water of condenser 2 by water inlet pipe 7 by water pump 5, carry out heat exchange with it, heat is taken out of by outlet pipe 8, and high temperature and high pressure gas is cooled to highly pressurised liquid.The gas-liquid mixed state that becomes low-temp low-pressure through throttling arrangement 3 enters evaporimeter 4 again, absorbs the airborne heat through blower fan 6, and the gas that becomes low-pressure low-temperature is got back to compressor 1.When the air source heat pump shown in the last figure is operated in atmospheric temperature and is higher than the capping temperature of temperature relay, under the effect of temperature relay, contactor 10 outages, magnetic valve 3c opens, 3a, 3b parallel connection, the double capillary operation will diminish the resistance that working medium flows through double capillary; When this heat pump is operated in following the prescribing a time limit of setting that atmospheric temperature is lower than temperature relay, under the effect of temperature relay, contactor 10 closures, magnetic valve 3c closes, and throttling arrangement moves in 3a single capillary mode, and it is big that the resistance when making working medium flow through single capillary becomes.So operation can make throttling arrangement be adapted to the air-source heat pump hot water operating condition of the whole year.
