Description
Affiliated technical field
The utility model relates to the Teat pump boiler technical field, especially relates to the Teat pump boiler of recyclable thermal wastewater waste heat.
Background technology
Teat pump boiler is to carry out the device of heat hot water from water or air the inside draw heat, and its advantage is: system is simple, stable, the thermal efficiency is high.Traditional Teat pump boiler be generally with bathroom outside air carry out heat exchange, hot gas during shower and hot water are all directly to emit, and shower time discharge spent hot water is contained a large amount of waste heats, also together is wasted.In order to realize spent hot water's waste heat recovery recycling, at present, also there are some Teat pump boilers that waste hot water heat recovery device is installed, to reclaim spent hot water's waste heat, thereby reach the purpose of energy-saving and emission-reduction.But, when low temp area running water temperature is very low, the speed of the recovery of heat pump heating is slow, the heating capacity deficiency of Teat pump boiler.
The utility model content
Problem to be solved in the utility model is to provide a kind of electrified heating, but the Teat pump boiler of fully recovering waste heat water waste heat.
Problem to be solved in the utility model, can realize by following technical scheme: a kind of three grades of waste water residual heat recovery type Teat pump boilers of electrified heating, include by compressor, condenser, the closure that choke valve and evaporimeter form heats loop, the storage tank that also comprises Teat pump boiler, collect spent hot water's main header tank and be serially connected in the heat exchanger on the running water inlet channel of storage tank, wherein condenser is arranged in storage tank, heat exchanger is arranged in main header tank, it is characterized in that: described evaporimeter comprises the first evaporimeter and the second evaporimeter, the first evaporimeter is located at the below of main header tank, the second evaporimeter is located at the below of the first evaporimeter, and the second evaporimeter is arranged in a secondary header tank, electric heater also is installed in described storage tank.
On the basis of the above, described main header tank is arranged on the bottom, bathroom.
The beneficial effect that adopts the utility model to bring: the utility model Teat pump boiler can utilize the water of saving in advance in secondary header tank, is used for the thermal source of draw heat when starting working as Teat pump boiler.The spent hot water's who produces after Teat pump boiler work heat, by three grades of waste heat recoveries, reclaims spent hot water's heat as much as possible.Visible the utility model can be at the Teat pump boiler prerequisite supplying heat source of starting shooting, make Teat pump boiler that enough heat absorption be arranged when starting working, can after Teat pump boiler work, can constantly from thermal wastewater, absorb heat again, carry out maintaining heat pump water heater required heat supplement of when normal operation, thereby avoid providing heat with a large amount of water.And, at low temp area, in the very low situation of running water temperature in winter, the heating capacity of Teat pump boiler can carry out auxiliary heating by electrical heating when not enough.
The accompanying drawing explanation
The structural representation of three grades of waste water residual heat recovery type Teat pump boilers that Fig. 1 is the utility model electrified heating.
The specific embodiment
As shown in Figure 1, a kind of three grades of waste water residual heat recovery type Teat pump boilers of electrified heating, include the closure formed by compressor 1, condenser 2, choke valve 3 and evaporimeter and heat loop, also comprise Teat pump boiler storage tank 4, collect spent hot water's main header tank 5 and be serially connected in the heat exchanger 6 on the running water inlet channel of storage tank 4, wherein condenser 2 is arranged in storage tank 4, and heat exchanger 6 is arranged in main header tank 5.Described evaporimeter comprises the first evaporimeter 7 and the second evaporimeter 8, the first evaporimeter 7 is located at the below of main header tank 5, the second evaporimeter 8 is located at the below of the first evaporimeter 7, and the second evaporimeter 8 is arranged in a secondary header tank 9, in described storage tank 4, electric heater 10 also is installed.Described main header tank 5 is arranged on the bottom, bathroom.
The multiple function of recovering waste heat of the hot water for shower that the utility model Teat pump boiler has
When Teat pump boiler is started working, at first, secondary header tank 9 is filled to water (when Teat pump boiler is used for the first time), do initial heat source, Teat pump boiler is drawn the heat of the water in secondary header tank 9, and the water in storage tank 4 are carried out to heat pump to 55 ℃ or higher.While using hot water, 42 ℃ of hot water are from gondola water faucet 11 ejections, and the spent hot water finally is pooled in main header tank 5, and at first the spent hot water carries out first order heating to the running water of the heat exchanger 6 of flowing through, water after heating flows in the storage tank 4 of Teat pump boiler, realizes spent hot water's first order waste heat recovery.The spent hot water flows through after heat exchanger 6, and water temperature is down to 25-30 ℃ of left and right, then and the refrigeration working mediums in the first evaporimeter 7 carry out heat exchange, refrigeration working medium turns back in the compressor of Teat pump boiler after absorbing waste water residual heat, realizes spent hot water's second level waste heat recovery.The spent hot water flows through after the first evaporimeter 7, water temperature is down to 15-20 ℃ of left and right, finally flow in secondary header tank 9 and carry out heat exchange with the second evaporimeter 8 interior refrigeration working mediums, refrigeration working medium turns back in the compressor of Teat pump boiler after absorbing waste water residual heat, realizes spent hot water's third level waste heat recovery.The spent hot water is down to 5-7 ℃ of left and right and drains from the bottom of main header tank 1 after three grades of waste heat recoveries.In the process of Teat pump boiler work, first order waste heat recovery is that nature has conducted heat and do not need to consume any energy, the second level and third level waste heat recovery are by compressor, the heat of absorption to be promoted to tap water heating, and its power consumption is 1/6 left and right recovered energy.
The auxiliary electrical heating function that the utility model Teat pump boiler has
At low temp area, the running water temperature in winter is very low, when the heating capacity of Teat pump boiler is not enough, starts electrical heating 8 auxiliary heatings, supplements not enough heat.In addition, when first case water of water tank, do not have the heat recovery of hot water for shower can start auxiliary electrical heater 10 yet and carry out heat hot water.
