Abstract
The utility model relates to a laminated hot pump with dual condensers, which can carry out temperature rise with large temperature difference. The laminated hot pump is composed of two compressors, an evaporator, an evaporative condenser, a condenser, two expansion valves, etc., wherein the rear part of an end (II) of the evaporative condenser is connected in series with the condenser as a low temperature condenser which is connected in series to a high temperature condenser through a condensing waterway, and a low temperature and a high temperature circulating systems are respectively formed. The utility model is characterized in that cooling water in the systems is heated step by step, so that the temperature difference of heat transmission between the cooling water and working substance at the high temperature side is reduced, and the heat exchange in the evaporative condenser can be balanced through the heat exchange regulation of the low temperature condenser. Therefore, the performance of the laminated hot pump can be effectively improved, and simultaneously the heat-supplying efficiency is greatly increased.
Description
Technical field
The utility model belongs to heat pump techniques, is specifically related to a kind of double-condenser cascade type heat pump system of temperature difference intensification greatly that has.
Background technology
Its function of cascade type heat pump mainly is to can be used as the heat pump assembly that the big temperature difference heats up, and comprising low temperature level and two circulations of high temperature level, evaporative condenser is the jockey of low temperature level and high temperature level, and the condenser that is the low temperature level is again the evaporimeter of high temperature level.At present the subject matter that exists of cascade type heat pump system is: in (1) present cascade type heat pump, catalyst carrier water only heats up by one step of condenser of high temperature level, and the temperature of rising is more limited.(2) heat exchange of evaporative condenser is heat exchange between high temperature level and the low temperature level working medium in the cascade type heat pump system, is difficult to heat pump the two poles of the earth and matches optimum state.Problem in view of present cascade type heat pump exists has become at present necessary so develop a kind of heat pump that not only can improve the temperature of catalyst carrier but also heat pump the two poles of the earth are complementary.
Summary of the invention
At the problem that existing cascade type heat pump exists, the purpose of this utility model is to propose a kind of simple in structure, reliable two condensation cascade type heat pump system.
Its structural principle of the utility model as shown in drawings.Cascade type heat pump mainly is made up of two compressor 1-1,1-2, evaporimeter 2, evaporative condenser 3, condenser 4-1,4-2, two expansion valve 5-1,5-2 and control valve 7.Wherein the I of evaporative condenser end is the import of low temperature level working medium, and the II end is low temperature level sender property outlet, and the III end is the import of high temperature level working medium, and the IV end is high temperature level sender property outlet.Connected a condenser 4-1 as low temperature level condenser at the II of evaporative condenser 3 end, low temperature level condenser 4-1 and high temperature level condenser 4-2 have been together in series by condensation water route 6.Form the low temperature level circulation of heat pump by compressor 1-1, evaporimeter 2, evaporative condenser 3, low temperature level condenser 4-1, expansion valve 5-1; Form the circulation of high temperature level by compressor 1-2, evaporative condenser 3, high temperature level condenser 4-2, expansion valve 5-2.Flow and water temperature that heat pump is regulated condensation water route 6 by control valve 7.
The beneficial effects of the utility model are: in system cooling water is carried out substep and heat up, not only reduced the heat transfer temperature difference of high temperature level side working medium and cooling water, and the heat exchange by low temperature level condenser is regulated and can be reached the heat exchange balance that makes in the evaporative condenser, except can effectively improving the performance of cascade type heat pump system, make the heating efficiency of system be highly improved simultaneously.
Description of drawings
Accompanying drawing is each assembly connection diagram of the utility model.
Among the figure: first order compressor 1-1; High stage compressor 1-2; Evaporimeter 2; Evaporative condenser 3; Low temperature level condenser 4-1; High temperature level condenser 4-2; Low temperature level expansion valve 5-1; High temperature level expansion valve 5-2; Condensation water route 6; Waterway regulating valve 7.
The specific embodiment
The total thermic load of the present embodiment heat pump is 6KW, in the circulation of low temperature level, evaporating temperature is 10 ℃, evaporating pressure is 0.57MPa, low temperature level working medium is absorbed heat in evaporimeter and is become equality of temperature with the gaseous state of depressing by the gas-liquid mixed attitude, enter the low temperature stage compressor then, in the low temperature stage compressor, be compressed into 76.2 ℃, the gaseous state of 1.96MPa, enter evaporative condenser afterwards and be condensed into 51.7 ℃, the liquid state of 1.95MPa, become 5.1 ℃, the gas-liquid mixed attitude of 0.57MPa through the choke valve step-down again, enter the evaporimeter heat absorption then, so finish the circulation of low temperature level.In the circulation of high temperature level, high temperature level working medium is absorbed heat in evaporative condenser, become equality of temperature with the gaseous state of depressing by 44.8 ℃, the gas-liquid mixed attitude of 0.72MPa, enter the high temperature stage compressor then, in the high temperature stage compressor, be compressed into 115.9 ℃, the gaseous state of 1.47MPa, enter condenser afterwards and be condensed into equality of temperature, become 44.8 ℃, the gas-liquid mixed attitude of 0.72MPa by the choke valve throttling again with the saturated liquid state of depressing, enter the evaporative condenser heat absorption then, so finish the circulation of high temperature level.The circulation of two condensation cascade type heat pumps water route is different from common cascade type heat pump circulation, the water route is through passing through high temperature level condenser again after the low temperature level condenser, according to regulating the water route, not only heat pump the two poles of the earth are mated but also can improve heat utilization efficiency like this, improve the efficient of heat pump.
This kind heat pump experimental system is safe and reliable to operation, is 2.6 through the COP value that calculates this experimental system.
