Description
Technical field:
The utility model is a kind of semi instant heating heat-pump water heater, belongs to the renovation technique of heat-pump water heater.
Background technology:
Existing heat-pump water heater mainly contains heat-pump water heaters such as air source, underground water source, Tu Yuan at present according to the difference of utilizing thermal source.Wherein be most widely used with air source heat pump again, than the hot water apparatus of fuel oil, combustion gas and electric heating, the efficiency of utilization of above-mentioned heat-pump water heater exceeds more than 3-6 times.
Existing heat-pump water heater is a heat accumulating type all almost: the hot water that is about to work long hours and produces, leaving one in is incubated preferably among the water tank standby, so just make the user need long heating can obtain hot water, particularly for the domestic consumer: promptly will must wait for the long time (for example more than 2 hours) before use, heat pump wants the long period to work under HTHP simultaneously, reduced the efficient of system, and reduced the functional reliability of system, in the back attemperater of finishing using, there is the hot water that is higher than serviceability temperature in a large number again simultaneously, heat in these hot water is most of can be dissipated before using next time, cause bigger thermal waste, offset the energy-saving effect of heat pump assembly to a great extent.
For this reason, the insider considers to adopt the technical scheme that realizes instant-heating by the power output of adjusting heat pump, so just can fully phase out attemperater, and the operating temperature that makes system is reduced to rationally with interval efficiently, being that the most favourable heat pump heats mode, also is the scheme that the most convenient user uses, and the shortcoming that still this scheme exists is that the volume of device is bigger, cost is higher, so that reduce the competitiveness of product in market.
The utility model content:
The purpose of this utility model is to consider the problems referred to above and a kind of stand-by period that had both reduced the user is provided, reduces the semi instant heating heat-pump water heater of the working time of heat pump under HTHP again.The utility model can reduce the volume of attemperater, reduces cost, and can reduce the waste of amount of residual heat will, and energy-saving effect is remarkable.
The technical solution of the utility model is: include heat pump and attemperater, wherein heat pump includes the compressor that connects successively with pipeline, condenser, throttling arrangement and evaporimeter, the water inlet of condenser is connected with municipal water inlet, the warm water outlet of condenser is connected with the water inlet of attemperater, wherein be connected with the circulation heating pump by pipeline between the water inlet of the hot water outlet of attemperater and condenser and be connected with and prevent to avoid in use cold water just to enter the check-valves of attemperater, and the outlet of the warm water of the hot water outlet of attemperater and condenser is connected with the water inlet that mixes water valve without the condenser heating.
The delivery port of above-mentioned mixed water valve directly is user's a water nozzle, or is connected with user's water pipe or tap.
The utility model is owing to be connected with the structure of circulation heating pump and check-valves by pipeline between the water inlet of the hot water outlet of employing attemperater and condenser, heat-pump water heater heats the cold water of attemperater earlier before use, reach design temperature until temperature, in use, from the cold water of running water pipe before mixing water, earlier become slightly high warm water through heat pump, mixing the back with the hot water that is kept at attemperater then uses for the user, because the warm water temperature that is used to mix is higher than running water, so the attemperater of this device is much smaller than the attemperater of the split type Teat pump boiler of routine, simultaneously owing to just need to carry out preheating before use, heat time heating time and temperature retention time are short, so the insulation requirement of attemperater can reduce significantly.With respect to much less preheating time of conventional heat pump water heater, attemperater is much smaller, and the short periods such as user's summary just can use, and reduce the power consumption of unit hot water production, and improve the reliability of equipment, and the operating temperature of heat pump and pressure are all lower, and heating efficiency is higher.Simultaneously, volume of the present utility model and cost are littler, lower than the immediate heating type heat pump of frequency conversion.The ratio of consumed power (quantity of heat production with) can reach more than 4～7 times when leaving water temperature is low the utility model because the efficiency ratio of heat pump, and therefore comparable existing electric heater is energy-conservation more than 80%.The utility model is that a kind of design is ingenious, function admirable, convenient and practical semi instant heating heat-pump water heater.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include heat pump and attemperater 5, wherein heat pump includes the compressor 1 that connects successively with pipeline, condenser 2, throttling arrangement 3 and evaporimeter 4, the water inlet 12 of condenser 2 is connected with municipal water inlet 9, the warm water of condenser 2 outlet 11 is connected with the water inlet 13 of attemperater 5, wherein be connected with circulation heating pump 6 by pipeline between the water inlet 12 of the hot water outlet 10 of attemperater 5 and condenser 2 and be connected with and prevent to avoid in use cold water just to enter the check-valves 7 of attemperater 5, and the warm water of the hot water outlet 10 of attemperater 5 and condenser 2 outlet 11 is connected with the water inlet of mixed water valve 8 without condenser 2 heating.The compressor 1 of heat pump, condenser 2, throttling arrangement 3 and evaporimeter 4 usefulness pipelines are communicated with into closed system successively, fill in the system with suitable working medium (cold-producing medium), other has electric controller in order to the control compressor operating, and in addition, electric controller also can be used to control the work of parts such as water pump simultaneously.The check-valves 7 that is equipped with between above-mentioned condenser 2 and the attemperater 5 can prevent that in use 2 heating just do not enter attemperater 5 to running water through condenser.In the present embodiment, above-mentioned evaporimeter (4) is air-cooled evaporimeter.
Use for ease of the user, the delivery port of above-mentioned mixed water valve 8 directly is user's a water nozzle, or is connected with user's water pipe or tap.
Operation principle of the present utility model is as follows: after cold water enters attemperater fully and fills with, promptly wait for user's preheating instruction, be in stand-by state, after obtaining the preheating instruction, heat pump and the circulation heating pump 6 be made up of compressor 1, condenser 2, throttling arrangement 3 and evaporimeter 4 promptly start operation, the cold water of beginning heat tracing water tank, after its temperature reached design temperature, system-down waited for that the user uses; When the user brings into use, the check-valves 7 and the circulation heating pump 6 of system are closed, behind the necessary condenser 2 and lifting temperature through heat pump earlier of the cold water of running water, hot water square and in the attemperater 5 mixes, because and the coolant-temperature gage that hot water mixes is slightly high, make the attemperater 5 of smaller size smaller that the mixing warm water of long period can be provided, simultaneously, the heat pump of this moment is between the rational high efficient area of operating temperature, the operating temperature of heat pump and pressure are all lower, and heating efficiency is higher.
Because it is integrated that the utility model is easy to realize, simplified split type Teat pump boiler unit user's installation process: no longer need to connect the freon pipe road during installation, only need to connect water pipe and get final product, easy to install and use.
