Abstract
The utility model relates to a low -grade heat utilization technical field, low -grade heat utilization device specifically says so. This low -grade heat utilization device includes: heat pump, compression pump, expansion valve and water temperature control system, the water temperature control system includes: hot -water tank, cold water storage cistern, water temperature regulater, hot -and -cold water mixer and heater. The device absorbs through the heat of heat pump in with low -grade heat energy, shifts into hydrothermal form output with the heat by the compression pump, adjusts the hydrothermal temperature that obtains through the water temperature control system, makes low -grade heat utilization device can provide the hot water of constancy of temperature for the user. The utility model provides a pair of low -grade heat utilization device can realize the recycle of low -grade heat energy, and has the stable characteristics of heat of output, get up these free heat utilizations, play energy -concerving and environment -protective effect.
Description
Technical field
The utility model relates to a kind of low grade heat energy and utilizes technical field, is that a kind of low grade heat energy utilizes device specifically.
Background technology
In different industrial application, can produce a large amount of used heat, these used heat are often by directly discharged in air or waste water, and the heat comprised is not only all by wasting in vain, and meanwhile, the hot water emission more than 30 DEG C, to underground, can cause thermal pollution.
In low-grade heat energy recirculation system, generally the Land use systems of used heat is often only achieved and the heat in used heat is extracted by heat exchanger.And adopt heat pump techniques to carry out Appropriate application to this low-grade heat energy, be a kind of feasible method and approach of Waste Heat Recovery.Due in industrial processes produce various used heat and belong to low grade heat energy, except the feature that temperature is relatively low, also often there is the feature of heat instability, thus cause the heat utilizing heat pump techniques to change also to be in dynamic changing process always.Traditional often meticulous not to the utilization of heat energy for low grade heat energy recycling device at present, the heat obtained often neither a metastable numerical value, so traditional low grade heat energy recycling device well can't meet the need of application.
