Description
Technical field
The utility model relates to the source pump that a kind of two-stage heats, especially a kind of source pump that can obtain higher temperatures hot water under low-temperature heat source.
Background technology
Heat pump is by consuming certain electric energy, the transfer of heat contained in low-temperature heat source to the equipment in hot water.The thermal power transfer of low-temperature heat source (low-grade heat source) can be high temperature (high-grade) heat energy that can directly utilize by it, does not need to consume a large amount of coal, combustion gas, oil, electricity etc. again and obtains, thus reaches the object of saving the high potentials such as coal, combustion gas, oil, electricity.Because heat pump has good energy-saving effect, reduce power consumption, thus decrease the discharge of carbon dioxide, sulfur dioxide isothermal chamber gas and toxic gas, decrease the discharge and atmosphere pollution etc. of carbon, therefore heat pump becomes one of current most popular energy-conserving and emission-cutting technology, has great development prospect.
Traditional source pump is in the process of heating operation, and when heat source temperature is lower, because heat source temperature and hot water temperature's temperature difference are large, heat pump efficiency significantly reduces, and heating capacity also significantly reduces, and the temperature difference is larger, and effect is poorer.
Traditional source pump is under low-temperature heat source, and heating capacity and Energy Efficiency Ratio are all very low, and along with the increasing of the temperature difference, the system of the inverse Carlow principle work of utilization draws and release heat all can be more and more difficult, and the running of unit is restricted.
Summary of the invention
Therefore, the purpose of this utility model is that providing a kind of significantly can reduce every evaporation of one-level refrigerant circuit system and the temperature difference of condensation working medium, allow every one-level coolant system have higher Energy Efficiency Ratio, thus improve overall heating capacity and efficiency, higher temperatures hot water can be obtained under low-temperature heat source.
The purpose of this utility model realizes like this.
The source pump that a kind of two-stage heats, comprise elementary refrigerant loop and secondary refrigerant loop, elementary refrigerant loop comprises the first compressor, heat exchanger, first throttle unit and evaporimeter, secondary refrigerant loop comprises the second compressor, condenser, heat exchanger, the second throttling unit, described elementary refrigerant loop and secondary refrigerant loop share a heat exchanger, described heat exchanger comprises two refrigerant lines, article one, refrigerant line is connected to elementary refrigerant loop, and another refrigerant line is connected to secondary refrigerant loop.
The source pump that two-stage heats, Entry-level System is from low-temperature heat source draw heat, its temperature increase to moderate temperature level, pass to level two again because its intrasystem condensation temperature and the evaporating temperature temperature difference less, can evaporating temperature reduce more, and the heat drawn is also just more therefore, improve heating capacity, then level two is delivered to heat lift in hot water to higher temperature again, makes unit can obtain the hot water of higher temperature.The source pump that two-stage heats, almost the temperature difference between thermal source and hot water is split into two halves, Entry-level System from thermal source draw heat, its temperature increase to moderate temperature level, pass to level two again, level two is delivered to heat lift in hot water to higher temperature again.Simple figuratively as water pump will be transported to eminence water, so difference in height is larger, and flow is fewer, and two-stage heats as adding a water pump in half eminence, and the effect of so carrying is certainly than only good with a water pump.Therefore, the source pump that two-stage heats can obtain higher temperatures hot water under low-temperature heat source.
Accompanying drawing explanation
Fig. 1 is fundamental diagram of the present utility model.
Detailed description of the invention
By reference to the accompanying drawings, the utility model is described in further detail.
The source pump that a kind of two-stage heats, comprise elementary refrigerant loop A and secondary refrigerant loop B, the operation principle in elementary refrigerant loop is as follows: the first Working medium gas sprays from compressor 1 exhaust outlet, becoming high temperature and high pressure gas enters in heat exchanger 2, in heat exchanger 2, the first working medium passes through heat exchange, heat is delivered in level two, reduce the temperature of the first working medium, make the first working medium of high-pressure gaseous at heat exchanger 2 inner condensat liquid, first working medium becomes liquid state from gaseous state, then the first working medium is allowed to become low temperature liquid through throttling unit 3, enter in evaporimeter 4, because in evaporimeter 4, the first power pressure reduces suddenly, the first working medium is made to vaporize in evaporimeter 4, evaporimeter 4 and low-temperature heat source carry out heat exchange, reach the object of absorbing heat from environment, the first Working medium gas after vaporization is got back to compressor 1 and is carried out next round circulation.
The operation principle in secondary refrigerant loop is as follows: the second Working medium gas sprays from compressor 5 exhaust outlet, becoming high temperature and high pressure gas enters in condenser 6, in condensation, the second working medium passes through heat exchange, heat is delivered in water, reduce the temperature of the second working medium, make the second working medium of high-pressure gaseous at condenser 6 inner condensat liquid, second working medium becomes liquid state from gaseous state, then the second working medium is allowed to become low temperature liquid through throttling unit 7, enter in heat exchanger 2, second working medium is vaporized absorb the heat of the first working medium in heat exchanger after, draw the heat passed over from Entry-level System.Dual unit heat driven heat pump unit by such form constantly from low-temperature heat source draw heat heat.
In above-mentioned two-stage refrigerant loop, be provided with two refrigerant lines in heat exchanger 2, a refrigerant line is connected to elementary refrigerant loop, and another refrigerant line is connected to secondary refrigerant loop.
