The double-pipe heat exchanger is used for heating water in the heat insulation water tank by the aid of the heat of the heat pump water heater. The problem that a traditional heat pump water heater is low in efficiency when used for heating water in the heat insulation water tank can be resolved by means of the control device.

Description

A kind of control device with the water in the heat pump water-heating machine heat tracing water tank
Technical field
The utility model relates to a kind of device that water is heated, and specifically is a kind of control device with the water in the heat pump water-heating machine heat tracing water tank.
Background technology
The numerous domestic hot-water's demands of Chinese population are big, produce the domestic hot-water and need consume a large amount of energy, China is an energy starved country per capita, and energy supply and demand is particularly thorny, greatly develop and adopt the energy-conserving and environment-protective mode to produce the domestic hot-water, significance is arranged for solving the China's energy problem.
The attemperater moisturizing of traditional Teat pump boiler is to adopt float switch to carry out moisturizing, running water directly enters attemperater by float switch control, directly mix with hot water in the attemperater, mixed water enters Teat pump boiler by water pump and heats and return attemperater, and higher this of mixed coolant-temperature gage is in the inefficient duty of high load capacity when causing Teat pump boiler that mixing water is heated.
The signal of the high water level switch (6) of the utility model by detecting attemperater, middle water level switch (7), low-water level switch (8), control water compensating valve (12) makes the lower running water of temperature directly enter Teat pump boiler, enter attemperater after the heating again, because it is lower to enter the water temperature of Teat pump boiler, state is realized energy-conservation thereby Teat pump boiler is in the underload efficiency operation.
The utility model content
The purpose of this utility model is to reduce the water temperature that enters Teat pump boiler, realizes energy-conservation thereby make Teat pump boiler be in underload efficiency operation state.
For realizing above-mentioned target, the utility model has adopted following technical scheme:
Control device with the water in the heat pump water-heating machine heat tracing water tank is characterized in that: comprise compressor (1), double pipe heat exchanger (2), choke valve (3), evaporimeter (4), attemperater (5), high water level switch (6), middle water level switch (7), low-water level switch (8), water pump (9), check valve A (10), check valve B (11), water compensating valve (12) and running water adapter (13).Double pipe heat exchanger (2) is to utilize the heat of heat pump water-heating machine that the water in the attemperater is heated.Running water enters double pipe heat exchanger (2) after taking over (13), water compensating valve (12), check valve B (11) through running water.Enter double pipe heat exchanger (2) behind water process water pump (9) in the attemperater, the check valve A (10).Attemperater (5) is provided with high water level switch (6), middle water level switch (7), low-water level switch (8).
Wherein double pipe heat exchanger (2) is to utilize the heat of heat pump water-heating machine that the water in the attemperater is heated.
Wherein high water level switch (6), middle water level switch (7), low-water level switch (8) are to be used for detecting the water level of attemperater (5) and signal being provided.
The utility model adopts singlechip controller, singlechip controller detects high water level switch (6), the middle water level switch (7) of attemperater, the signal of low-water level switch (8) in real time, the water level of attemperater will reduce when the user used hot water, when high water level switch (6) and middle water level switch (7) are in when disconnecting, control water compensating valve (12) makes the lower running water of temperature (temperature of running water is generally 10~25 ℃) directly enter the double pipe heat exchanger (2) of Teat pump boiler, be heated to 55 ℃ and enter attemperater again, until high water level switch (6) closure.Because the water temperature lower (10~25 ℃) that enters double pipe heat exchanger (2), thereby at this moment Teat pump boiler is in underload efficiency operation state and realizes energy-conservation.
The attemperater moisturizing of traditional Teat pump boiler is to adopt float switch to carry out moisturizing, the water level of attemperater will reduce when the user uses hot water, 10~25 ℃ running water directly enters attemperater by float switch control, directly mix with 50~55 ℃ of hot water in the attemperater, 0.5~5 ℃ (this depends on the temperature that covers the running water that comes to mix back coolant-temperature gage reduction, the hot water capacity of rate of water make-up and attemperater), mixed water enters Teat pump boiler by water pump and heats and return attemperater, so constantly circulation reaches design temperature (general design temperature is 55 ℃) until water tank temperature, at this moment Teat pump boiler is in the inefficient duty of high load capacity, and energy resource consumption is more energy-conservation.
After the utility model adopts technique scheme, can have following beneficial effect: be in the bigger problem of high load capacity poor efficiency energy resource consumption when having solved Teat pump boiler moisturizing heat.
