Abstract
The utility model discloses a double-heat-source evaporator for a heat pump. The double-heat-source evaporator is composed of copper pipes, fins and a fan. According to the copper pipes, two small copper pipes are arranged inside a large copper pipe in a sleeved mode, the copper pipes are bent into U-shaped components, penetrate through the fins and mainly comprise a refrigerating fluid copper pipe and a hot water copper pipe, the hot water copper pipe is arranged in the central symmetrical area of the fins, and the refrigerating fluid copper pipe surrounds the hot water copper pipe. The refrigerating fluid copper pipe, the hot water copper pipe and a solar water heating system form a closed loop. The evaporator integrates a water source evaporator and an air source evaporator. The double-heat-source evaporator is small and compact in structure, the number of evaporators of a heat pump system can be reduced, the initial investment is reduced, and the occupied area is reduced at the same time. Water side heat exchange and air side heat exchange can be achieved in the double-heat-source evaporator, so that a water system pipeline of the system becomes simple. Water side heat exchange can be carried out when air side heat exchange is carried out, and the heat exchange efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of evaporimeter, specifically relates to a kind of various occasions that need transfer of heat that are applied to, and especially has the utilizable environment of Low Temperature Thermal.
Background technology
Along with the continuous propelling of country to energy-saving and emission-reduction work, tap a new source of energy and become the task of the current most important thing of China with power-saving technology.The low-temperature heat source of conventional heat pump is single, common are single water source thermal source and air-source thermal source, but different thermals source has different operating characteristics, using respectively that they will inevitably be subject to regional limits as the use region of the heat pump of low-temperature heat source.Meanwhile, system exists that function singleness, solar energy heating efficiency are lower, the not high problems of comprehensive utilization rate of systems.In order to solve these deficiencies, we have proposed two thermal source evaporimeters for a kind of heat pump, and this pair of thermal source evaporimeter is not only simple and compact for structure, and only needs an evaporimeter, have so just greatly saved occupation of land space and cost; When solar energy intensity does not meet standard, when carrying out the heat exchange of wind side, also can carry out the heat exchange of water side simultaneously, so just improve greatly heat exchange efficiency.
Utility model content
The deficiency existing for prior art, the utility model provides two thermal source evaporimeters for a kind of heat pump, and concrete is the sleeve-type heat exchanging pipe of inside increase that can realize at the heat exchanger tube of original evaporimeter.So, cold-producing medium can be realized water side and the heat exchange of wind side in same evaporimeter, is equivalent to two heat exchangers.Two thermal source evaporation structure compact, can reduce the number of units of heat pump evaporimeter, have reduced initial cost and have also reduced floor space simultaneously; In two thermal source evaporimeters, can realize the heat exchange of water side and the heat exchange of wind side, make the water system pipeline of system become simple; And can carry out the heat exchange of water side in the heat exchange of wind side, greatly improved heat exchange efficiency.
With two thermal source evaporimeters, by copper pipe, fin and blower fan, formed, what copper pipe adopted is 2 little copper pipes of large copper pipe inner sleeve, and copper pipe curves U-shaped portion part and passes through fin and mistake, and this copper pipe mainly comprises cold-producing medium copper pipe and hot water copper pipe.Hot water copper pipe is positioned at the Central Symmetry region of fin, and refrigerant pipe lays respectively at the surrounding of hot-water line; Cold-producing medium copper pipe, hot water copper pipe and solar water heating system have formed a closed loop.It is to catchment source and air-source evaporimeter in the evaporimeter of one.Two thermal source evaporimeters adopt double pipe heat exchanger, and at the additional fin of double-tube heat exchanger, in the middle of sleeve pipe, are cold-producing medium, are the hot water from solar water heating system in sleeve pipe inner tube.Radiating fin is characterised in that cold-producing medium copper pipe and fin link together, and is enclosed within cold-producing medium copper pipe in hot water copper pipe.Source pump is transmitted to cold-producing medium copper pipe by heat from hot water copper pipe when heating like this, thereby has improved the evaporating temperature of source pump; In defrost process, fin can absorb the heat in airborne heat and hot-water line, thereby accelerates the speed of defrost.
A kind of heat pump is characterized in that with two thermal source evaporimeters the material of copper pipe is red copper.The specification of cold-producing medium copper pipe is 30mm * 0.8mm, and the specification of hot water copper pipe is 10mm * 0.7mm.The spacing of fin is 3.2mm.
The beneficial effects of the utility model are that the hot water of generation can meet the refrigeration duty of heat pump when solar radiation energy is sufficient, and now, heat pump be take solar water as thermal source, and two thermal source evaporimeters absorb heat and meet indoor heating from hot water.When solar radiation is rich, by the hot water storage of redundance in water storage box, store heat.When solar radiation is not enough, solar water heating system and water storage box provide heat by the while to heat pump.When solar radiation is inadequate and outdoor temperature is not less than 3 ℃, simultaneously open water side heat exchange and the heat exchange of wind side, now cold-producing medium can be simultaneously from inner tube hot water and in outside air hot.When solar radiation is lower, open the drain valve in two thermal source evaporimeters, (now air themperature is lower for water in drain sleeve inner tube, preventing that water-ice in pipe from freezing makes interior pipe explosion), open blower fan simultaneously, now, heat pump will be take air as thermal source, absorb the refrigeration duty that heat meets air-conditioning system from outdoor air.

the specific embodiment:
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
Instantiation: in the winter time, we set a temperature value as 5 ℃ according to the environmental condition of Zhuzhou, and when outside air temperature is greater than 5 ℃, now the thermal efficiency of air source heat pump is higher, do not need the heat exchange of open water side, the heat exchange of wind side can meet the thermic load requirement of air-conditioning system.The hot water that now solar water heating system produces can be supplied with building domestic hot-water and be stored in heat collection water tank; When outdoor temperature is lower than 5 ℃ but also not frosting of evaporator fin, now open water side and the heat exchange of wind side simultaneously; Too low when outside air temperature, while opening the heat exchange of wind side, the easy frosting of evaporator fin, closes blower fan, stops the heat exchange of wind side, opens the valve of water storage box, hot water is entered and in evaporimeter, carry out heat exchange, and allow air-side heat exchanger defrost voluntarily.
