Detailed description of the invention
Embodiment 1
See figures.1.and.2, a kind of heat pump hot-water system with two kinds of heat exchange modes of the present utility model, comprise heat pump circulating system, the intermediate heat transfer circulatory system, water inlet pipe 7 and control valve, described heat pump circulating system comprises the compressor 1, evaporimeter 2, expansion valve 3 and the condenser 4 that form closed circuit.The described intermediate heat transfer circulatory system comprises the water pump 5 of composition closed circuit, the evaporimeter 2 for the heat exchanger 6 and described heat pump circulating system that absorb used heat.Described water inlet pipe 7 is communicated with the condenser 4 of described heat pump circulating system.Described control valve for the connection of the closed circuit and water inlet pipe 7 and condenser 4 that cut off the intermediate heat transfer circulatory system, and makes water inlet pipe 7 and evaporimeter 2, water pump 5, heat exchanger 6, condenser 4 form enhanced heat exchange stream.In the present embodiment, described control valve is four-way change-over valve 8, and four ports of described four-way change-over valve 8 connect evaporimeter 2, heat exchanger 6, condenser 4 and water inlet pipe 7 respectively.
With reference to Fig. 1, this heat pump hot-water system is with indirect cyclic process heat exchange work pattern, water inlet pipe 7 is communicated with condenser 4 by four-way change-over valve 8, and make the closed circuit of the intermediate heat transfer circulatory system be in closure state, the course of work of heat pump hot-water system: the intermediate heat transfer circulatory system absorbs waste water or waste-gas heat, heat pump circulating system absorbs intermediate heat transfer circulatory system heat by evaporimeter 2, then by condenser 4 heating cold water.In the course of work, water pump 5 continuous service.
With reference to Fig. 2, this heat pump hot-water system is with enhanced heat exchange work pattern, four-way change-over valve 8 makes water inlet pipe 7 be communicated with evaporimeter 2, and heat exchanger 6 is communicated with condenser 4, thus make water inlet pipe 7 and evaporimeter 2, water pump 5, heat exchanger 6, condenser 4 forms enhanced heat exchange stream, the course of work of heat pump hot-water system: cold water is through four-way change-over valve 8, first enter evaporimeter 2 to lower the temperature, then enter heat exchanger 6 and carry out heat exchange with waste water or waste gas, absorb the current after waste water or waste-gas heat intensification, enter condenser 4 through four-way change-over valve 8 again to heat up further, flow out for.This heat exchange pattern carries out heat exchange with waste water or waste gas again because cold water first pumps after heat is lowered the temperature, and greatly enhances heat transfer effect, be applicable to the place that cold water and waste water or the waste gas temperature difference are less than normal, and cold water temperature is not less than the place of 8 DEG C.In the course of work, water pump 5 can be out of service, and now cold water depends merely on intake pressure flowing; As required, water pump 5 also can run, and as tubing pump to increase hydraulic pressure, thus effectively can reduce operating noise and reduce energy consumption.
Further, the reservoir 10 for gas-liquid separation is provided with between described compressor 1 and evaporimeter 2.When vaporizing completely from evaporimeter 2 refrigerant out, liquid refrigerant can fall under gravity into the bottom of reservoir 10, thus compressor 1 sucks liquid and causes liquid hammer.
