Description
Technical field
It is specifically a kind of that there are the intermediate double high-efficiency heat pump systems of full liquid condensing the present invention relates to the technical field of heat pump system
System.
Background technique
As environment warms, each seasonal temperature variation gap is excessive, and the fixed air-cooled changes in temperature unit of frequency is difficult to bear summer height at present
Decaying, the ranges of operation such as the energy of middle benefit gas cryogenic refrigeration, winter heating are extremely limited, and cause energy consumption is high to increase.Comprehensive state
The enhancing of power, the existing very big development of China's power industry, China capacity of installed generator and annual electricity generating capacity low by the end of 1999
Respectively reach 2.988 hundred million kW and 1,223,100,000,000 kW, the second place of the world Jun Ju.But the growth of electric power does not still meet national warp
The fast development of Ji and the needs of people's lives electricity consumption sharp increase, national short of electricity situation do not obtain basic change yet.At present
Power supply shortage performance it is as follows: 1), load rate of grid it is low, system peak-valley difference is big, and peak power wretched insufficiency causes power grid to pass through
Often lock is connect to ration the power supply.2), urban electric power consumes rapid development, and urban distribution network does not adapt to, and causes electricity can't get into, under not
Situation.
However, current wind-cooling type heat pump is applied to high-temperature heat accumulation and low-temperature air conditioner cold-storage during the work time, in low temperature
While cold-storage or high-temperature heat accumulation, because being both to achieve the purpose that occupied area is small, high-energy is stored by heat exchange.Cause
And -35~15 DEG C of low-temperature evaporation temperature or 50~90 DEG C of condensation temperatures process at work, current is mainly manifested in following two
A aspect: one, heating capacity is gradually decayed with the decline (refrigerating capacity is then on the contrary) of environment temperature, and the size of inspiratory capacity is inhaled with it
Gas saturation temperature corresponds, and air-breathing saturation temperature is higher, and air-breathing is bigger, and vice versa.As environment temperature gradually declines, heat
Pumping system evaporating temperature reduces, and compressor air suction specific volume increases, and gas transmission coefficient reduces, and causes heating capacity to reduce, heat pump system energy
Effect accordingly declines than (COP).Two, parts operational reliability problem, especially compressor, at low ambient temperatures, evaporating temperature mistake
When low, the compression ratio increase of compressor causes excessive discharge temperature, causes heat pump system to be easy to appear back liquid, causes to press when serious
The damage of contracting machine.
Therefore existing heat pump structure remains to be further improved, while proposing will be by promoting low evaporating temperature accumulation of energy skill
Part peak load is transferred to low ebb and combined and reduces occupied area by art.
In the case where power supply shortage, the implementation of time-of-use tariffs policy, one kind have intermediate full liquid supercooling pair efficiently
The characteristics of heat pump and low evaporating temperature, high condensation temperature energy accumulating technique itself is low evaporating temperature, high condensation temperature energy accumulating technique
Application provide vast potential for future development.
