Abstract
The invention discloses a water circulation system of a heat pump water heater. The water circulation system of the heat pump water heater comprises a heat pump device and a heat-insulation water tank, wherein the heat pump device comprises a compressor, a condenser, a throttle valve and an evaporator which are serially connected to one another sequentially; the condenser is connected with the heat-insulation water tank through a circulation loop; the circulation loop comprises a water supplying branch and a water returning branch; water flow of the water supplying branch flows from the condenser to the heat-insulation water tank; and water flow of the water returning branch flows from the heat-insulation water tank to the condenser; the water returning branch is connected with a water replenishing branch which is connected with an external running water system; and the water replenishing branch is sequentially provided with a second filter, an electromagnetic valve and a second one-way valve along the flowing direction of the water flow. By the water circulation system of the heat pump water heater, normal-temperature running water can be prevented from entering the heat-insulation water tank directly.
Description
Technical field
The present invention relates to a kind of Teat pump boiler, particularly relate to a kind of water circulation system of Teat pump boiler.
Background technology
The attemperater of Teat pump boiler, in use need constantly to fill into running water, in prior art, running water normally directly fills in attemperater, cause the fluctuating temperature in attemperater thus, thus cause the water temperature of hot water temperature and the attemperater delivery port that Teat pump boiler shows not to be inconsistent, or there is sometimes hot and sometimes cold phenomenon, bring inconvenience to the life of people.
Summary of the invention
The present invention is intended to solve above-mentioned mentioned technical problem, provides a kind of and the tap water direct under normal temperature can be avoided to tap into water circulation system into attemperater.
The present invention is realized by following technical scheme:
A kind of water circulation system of Teat pump boiler, comprise heat pump assembly and attemperater, heat pump assembly comprises the compressor of connecting successively, condenser, choke valve and evaporimeter, wherein, condenser is connected with attemperater by closed circuit, described closed circuit comprises water supply branch road that current flow to attemperater by condenser and the backwater branch road that current are flowed to condenser by attemperater, flow direction along current on described backwater branch road is disposed with the first filter, water circulating pump and the first check valve, backwater branch road is also connected with the moisturizing branch road be connected with outside running water system, moisturizing branch road is disposed with the second filter along the flow direction of current, magnetic valve and the second check valve.
Preferably, the water side of described water supply branch road is higher than water inlet end.
Preferably, the two ends of described backwater branch road are connected with the bottom of condenser with the bottom of attemperater respectively; The two ends of described water supply branch road are connected with the top of condenser with the top of attemperater respectively.
Preferably, the two ends of described backwater branch road, the two ends of water supply branch road are provided with stop valve.
Preferably, described first filter, the second filter are Y-piece road filter.
Beneficial effect is: the water circulation system of Teat pump boiler of the present invention, by moisturizing branch road is connected with the backwater branch road of one-way flow, thus the running water under making normal temperature is just entering in attemperater after the heating of condenser, cause fluctuating temperature larger when avoiding the hot water in attemperater directly to mix with running water, and the working time of water circulating pump can also be reduced, be conducive to the consumption reducing electric energy.
Accompanying drawing explanation
Fig. 1 is the principle schematic of the water circulation system of Teat pump boiler of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The water circulation system of Teat pump boiler as shown in Figure 1, comprise heat pump assembly and attemperater 2, heat pump assembly comprises the compressor of connecting successively, condenser 1, choke valve and evaporimeter, wherein, condenser 1 is connected with attemperater 2 by closed circuit, closed circuit comprises water supply branch road 3 that current flow to attemperater 2 by condenser 1 and the backwater branch road 4 that current are flowed to condenser 1 by attemperater 2, backwater branch road 4 is disposed with the first filter 11 along the flow direction of current, water circulating pump 8 and the first check valve 13, backwater branch road 4 is also connected with the moisturizing branch road 5 be connected with outside running water system 10, moisturizing branch road 5 is disposed with the second filter 12 along the flow direction of current, magnetic valve 6 and the second check valve 14.The water circulation system of Teat pump boiler of the present invention, by moisturizing branch road 5 is connected with the backwater branch road 4 of one-way flow, thus the running water under making normal temperature can add to continuously in attemperater 2 after the heating through condenser 1, cause fluctuating temperature larger when avoiding the hot water in attemperater 2 directly to mix with running water, and the working time of water circulating pump 8 can also be reduced, be conducive to the consumption reducing electric energy.
Preferably, the water side of water supply branch road 3 is higher than water inlet end, thus the current on the running water of normal temperature and/or backwater branch road 4 can be made in condenser 1 to stop the longer time, to promote the temperature of the current on water supply branch road 3 and the effect being similar to check valve can be played.
Preferably, the two ends of backwater branch road 4 are connected with the bottom of condenser 1 with the bottom of attemperater 2 respectively; The two ends of water supply branch road 3 are connected with the top of condenser 1 with the top of attemperater 2 respectively.
Preferably, the two ends of backwater branch road 4, the two ends of water supply branch road 3 are provided with stop valve 9, are convenient to carry out repair and maintenance to water supply branch road 3 and backwater branch road 4.
Preferably, the first filter 11, second filter 12 is Y-piece road filter.
Above embodiment is only not limited in order to technical scheme of the present invention to be described, all do not depart from spirit and scope of the invention any amendment or equivalently to replace, it all should be encompassed in the scope of technical solution of the present invention.
