Background technology
Along with the raising of people's living standard, the popularity rate of air-conditioner rises year by year.Under the background nowadays advocating low-carbon economy, energy-saving and environmental protection become the theme of sustainable development.In total energy consumes, building energy consumption account for sizable proportion, and air-conditioning system is again one of main energy consumption of building, and current air conditioning energy consumption has reached more than 60% of building energy consumption, and the high flow rate of the energy causes very large pressure to China's development,
Ground-source heat pump host is when cooling in summer, and the heat extraction of unit is discharged by ground heat exchanger.Heat pump host work principle compresses-condensation-expand-evaporate such carnot's cycle process gone round and begun again to cold-producing medium.In sweat cooling process, a large amount of condensation heat needs to drain, if do not add utilization, will be discharged by ground heat exchanger, not only waste this part heat, and can cause larger impact to underground environment.Therefore, have the occasion of hot-cool demand at the same time, suitable recovering condensing heat, is used, and plays the effect of energy-saving and emission-reduction.
At present, mainly as shown in the table to the recuperation of heat mode of the Double-bundle list condenser of heat pump main frame:
Above-mentioned recuperation of heat ground-source heat pump host is under underground pipe side cooling water temperature is the normal operation of 30 DEG C-35 DEG C, and recuperation of heat side hot water temperature only has 40 DEG C-45 DEG C, does not reach the requirement of 50 DEG C-55 DEG C that hot water temperature requires.
Utility model content
For the defect of above-mentioned prior art, the utility model provides a kind of heat pump main frame total heat recovery system, can reclaim the condensation heat of heat pump main condenser, and can ensure that the hot water temperature of recuperation of heat side reaches the requirement of 50 DEG C-55 DEG C of hot water temperature's requirement.
To achieve these goals, the technical solution of the utility model is:
A kind of heat pump main frame total heat recovery system, comprise the closed-loop path be made up of the evaporimeter connected successively, compressor, condenser, described condenser is Double-bundle list condenser, the inside of described Double-bundle list condenser is provided with the water coil of two groups of parallel connections, the two ends of the water coil wherein described in a group connect underground pipe feed pipe and underground pipe return pipe respectively, the outlet pipe of the water coil described in another group connects domestic hot-water's case, and water inlet pipe connects running water pipe; Described underground pipe return pipe is provided with and controls the cooling water side water pump of backwater, described in connect running water pipe water inlet pipe on be provided with domestic hot-water side water pump.
As the improvement to technique scheme, described closed-loop path is provided with the expansion valve controlling fluid flow in closed-loop path between condenser and evaporimeter.Prevent the underutilization of evaporimeter 1 area and engine knock phenomenon.
As the improvement to technique scheme, described heat pump main frame total heat recovery system also comprises a temperature controller, and described temperature controller is electrically connected respectively with cooling water side water pump, domestic hot-water side water pump, domestic hot-water's case.
As the improvement to technique scheme, described domestic hot-water's case is provided with temperature sensor, and described temperature sensor is arranged on the connecting circuit of temperature controller and domestic hot-water's case.
During heat pump host work, what pass through inside condenser is the cold-producing medium of HTHP, normal-temperature water is delivered in condenser recuperation of heat coil pipe by domestic hot-water side water pump, normal-temperature water and high temperature refrigerant carry out heat exchange, water temperature is raised, enter domestic hot-water's case again, (50 DEG C about-55 DEG C are generally) when water tank temperature meets setting value, temperature sensor on domestic hot-water's case sends a signal to temperature controller, temperature controller sends signal more respectively to domestic hot-water side water pump and cooling water side water pump simultaneously, domestic hot-water side water pump then quits work, cooling water side water pump is started working.When the discharge reduction in domestic hot-water's case, water temperature reduce, the water replanishing device of domestic hot-water's case is by automatic water supplement, at this moment domestic hot-water's case temperature reduces, once water temperature drop to setting value (being generally about 45 DEG C), temperature sensor then sends a signal to temperature controller, temperature controller sends signal more respectively to domestic hot-water side water pump and cooling water side water pump simultaneously, cooling water side water pump stops, domestic hot-water side water pump is then started working, again the water of domestic hot-water's case is heated, until water temperature rises to design temperature.Like this, by ensureing the water temperature of domestic hot-water's case to the on off control of cooling water side water pump and domestic hot-water side water pump, when producing domestic hot-water, only allow in the same time to start domestic hot-water side water pump, cooling water side water pump must be stopped, prevent cooling water side water pump from draining heat, can hot water temperature be ensured completely thus.
Compared with prior art, the utility model has the following advantages:
1, recuperation of heat temperature is high.The recuperation of heat water temperature of conventional condenser is generally 30-35 DEG C, and the Double-bundle list condenser recuperation of heat of our research is by the start and stop of controlled cooling model water side pump, and hot water temperature can be made can to reach 50 DEG C-55 DEG C.
2, the condition of work of equipment is improved.Because increasing heat reclamation device on the basis of refrigeration plant, heightening the degree of supercooling of cold-producing medium, having added refrigerating efficiency, saved electric energy, extend equipment life.
3, freely obtain hot water, save the electricity consumption or fuel cost that use boiler.
4, the feature of environmental protection is good, decreases the heat exhaust of summer to underground environment, reduces the impact of underground environment.
5, heat reclamation device does not affect the normal work of refrigeration unit.
6, investment cost is reduced.
