Description

The Rapid Thermal pump hot water machine

Technical field

The utility model relates to a kind of heat-pump water heater that can start fast, belongs to the transformation and upgrade type of ordinary hot pump hot water machine.

Background technology

The existing heat-pump water heater of tradition 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, when the user uses hot water, cold water enters water tank hot water is ejected, when the water temperature of water tank because the entering to mix and cause cooling of cold water, when being lower than design temperature, unit starting heats, and the hot water time ratio that so just makes the user to use is shorter.Cold water enters hot water in addition, and it is very fast to cause water temperature to descend.Reduced the efficient of system, the user can only strengthen the water tank volume, but can causing again, increasing attemperater volume stop using rear water box to have a large amount of surplus hot waters, 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.

In view of above existing problems, the utility model provide a kind of safe and reliable, volume is little, capacity is big, the high Rapid Thermal pump hot water machine more than 20% of thermal efficiency ratio ordinary hot pump hot water machine.

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, and reduces the Rapid Thermal pump water heating apparatus of heat pump in insulation loss between non-delivery period 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: the water inlet at heat pump installs water route one-way pressure relief valve (11) and water inductive probe (6) additional, improves the control system (8) of heat-pump hot-water unit simultaneously; Wherein heating contains blower fan parts such as (5) by heat pump compressor (1), cross valve (2), hot water heat exchanger (3), throttling arrangement (4), evaporimeter and is connected in sequence with refrigeration piping; Comprise water inductive probe (6), hot water temperature's probe (7) and control system monitor components such as (8) composition in addition; The water inlet of hot water heat exchanger (3) is connected with municipal water inlet by the waterway channel of water inductive probe (6); The water route check valve that the three-way connection of the water inlet of hot water heat exchanger (3) connects is mainly used to prevent that cold water just enters attemperater without the condenser heating when external water circulating pump of user and attemperater; In addition, the user can be installed in water pump in the unit as required.

As long as this heat-pump water heater is sensed user's heat water or the hot water temperature is low excessively, all start-up system is carried out the hot water heating at once; When adopting attemperater, heat-pump water heater heats the cold water of attemperater earlier before use, reaches design temperature until temperature; In use, before entering water tank, become slightly high warm water through heat pump earlier, prevented that effectively the water of water tank from sharply descending, prolonged service time from the cold water of running water pipe.Because the warm water temperature that enters water tank is higher than running water, so this device to the requirement of the attemperater attemperater much smaller than the split type Teat pump boiler of routine, when the bigger main frame of employing power, can be cancelled attemperater.Because in use, unit can start rapidly, with respect to much less preheating time of conventional heat pump water heater simultaneously; The ratio of consumed power (quantity of heat production with) can reach more than 4 one 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, and convenient and practical heat-pump water heater, it can reduce user's stand-by period, also 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.
