Description
Technical field
The present invention relates to a kind of water heater, be specifically related to a kind of instant heating type heat pump water heater.
Background technology
Water heater is a kind of utensil of life with hot water that provide.Teat pump boiler is just obtaining increasing application as energy-conservation sharp weapon.But the storage-type Teat pump boiler is restricted on the fabricating yard because volume is bigger, really the user of ability usefulness and few.The less instant heating type heat pump water heater of volume is a kind of direction of future development, but does not also have ripe product on the market.Trace it to its cause, the one, during water use peak, general instant heating type heat pump water heater adds heat and does not catch up with, and leaving water temperature is attempted to keep with restriction discharge by some producer, has temperature not have water, and is inapplicable fully; Be exactly in addition when interrupted water, the compressor startup that can not make an immediate response does not have hot water.
Summary of the invention
In order to solve the deficiency that above-mentioned technology exists, the object of the present invention is to provide a kind of instant heating type heat pump water heater, this water heater heat fast, the water yield is sufficient.
Another object of the present invention is to provide a kind of control method of instant heating type heat pump water heater.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention realizes through following technical scheme:
A kind of instant heating type heat pump water heater; Comprise a compressor; Said compressor connects a condenser, and said condenser connects an expansion mechanism, and said expansion mechanism connects an evaporimeter; Said evaporimeter connects said compressor, also is connected with a magnetic valve between the outlet of said compressor and the inlet of evaporimeter.
Further, the hot water outlet place of said condenser is provided with a temp probe, and said temp probe connects a controller, and said controller connects said magnetic valve and compressor respectively.
Further, said compressor is a frequency-changeable compressor.
Further, said condenser inner refrigerant and water are adverse current.
A kind of control method of instant heating type heat pump water heater is characterized in that, comprises step:
The said temp probe of step 1) is surveyed the temperature of the hot water outlet of said condenser, and this temperature value is transferred to said controller;
Step 2) said controller carries out difference with temperature detected in the step 1 and predefined temperature and calculates;
Step 3) is according to the difference of calculating in the step 2, and said controller is adjusted the rotating speed of said compressor, and difference is big more, and the rotating speed of said compressor is fast more.
Further, before step 1, if said compressor is in stopped status, then, said magnetic valve is opened in the control of said controller, makes to be able to the rapid balance of high and low pressure energy of said compressor can start once more at short notice.
Principle of the present invention is following:
The cooling water inlet of running water on condenser, get in the condenser, the refrigerant gas of the HTHP of discharging from compressor gets into condenser, emits heat; The water of heating process from condenser; Cold-producing medium is emitted heat and is condensed into highly pressurised liquid, and highly pressurised liquid is through step-down cooling behind the expansion mechanism, and low-temperature refrigerant is through evaporator heat absorption vaporization; The machine that is compressed sucks, after compressor compresses, becomes again gas, entering condenser, the so circulation of warm high pressure.In the process of water, the rotating speed of compressor changes along with the difference of the leaving water temperature of condenser delivery port temp probe induction and design temperature, and difference is big more; The rotating speed of compressor is fast more; In condenser, cold-producing medium and water are adverse current in addition, so just can as soon as possible water temperature be elevated; In addition, after compressor shutdown, magnetic valve is opened, and makes the rapid balance of high and low pressure energy, the compressor of compressor be able to can start once more at short notice.
Compared with prior art, beneficial effect of the present invention is following:
Instant heating type heat pump water heater of the present invention has overcome that storage-type Teat pump boiler volume is big, and instant electric water heater's power is big, power consumption is big, other instant heating type heat pump water heaters heat unhappy and the problem that the water yield is not enough.And instant heating type heat pump water heater of the present invention is simple in structure, easy to operate.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
