Description

Improved vapour compression refrigeration system of cluster and uses thereof

Technical field

The present invention relates to vapour compression refrigeration system and uses thereof, particularly relate to improved vapour compression refrigeration system of cluster and uses thereof, being applicable to family and unit provides the washing of having a bath and live with hot water, drinking water, hot-water type heating in winter, wet monsoon cold mould air-conditioning or cooling-and-warming splitting formula air-conditioning the whole year; Or cold water type air-conditioning; Or industrial and agricultural production with hot water and boiling water, can also provide refrigerating capacity for freezer, refrigerator, refrigerator or refrigerator; For dryer and drying shed provide heating capacity.

Background technology

Its vapour compression refrigeration system of existing heating-cooling equipment does not have subcooler, its coefficient of refrigerating performance ε 1=q 1/ W 0(1), its coefficient of heat supply ε 2=q 2/ W 0(2), q in the formula 1Be the refrigerating capacity of system of unit cryogen in the evaporimeter, unit is kJ/kg; q 2Be the heating load of system of unit cryogen in the condenser, unit is kJ/kg; W 0Be the work done during compression that compression system of unit refrigerant vapour in the compressor consumes, unit is kJ/kg;

As Figure 17: its cold-producing medium of heating-cooling equipment is pressed shown in the enthalpy diagram,

q 1=h 1-h 3…(3);q 2=h 2-h 3…(4);W。=h 2-h 1…(5)。

So ε 1=q 1/ W 0=(h 1-h 3)/(h 2-h 1) ... (6); ε 2=q 2/ W 0=(h 2-h 3)/(h 2-h 1) ... (7)

Cluster of the present invention is equipped with the coefficient of refrigerating performance of its vapour compression refrigeration system of heating-cooling equipment of subcooler: for

ε′ 1=q 1′/W 0=(h 1-h 4)/(h 2-h 1)=[(h 1-h 3)+(h 3-h 4)]/(h 2-h 1)=ε 1+(h 3-h 4)/(h 2-h 1)……(8)

ε′ 2=q 2′/W 0=(h 2-h 4)/(h 2-h 1)=[(h 2-h 3)+(h 3-h 4)]/(h 2-h 1)=ε 2+(h 3-h 4)/(h 2-h 1)…(9)

By formula (8) and (9) as can be seen cluster the coefficient of refrigerating performance ε ' of its vapour compression refrigeration system of heating-cooling equipment of subcooler is housed 1, coefficient of heat supply ε ' 2Respectively greater than its coefficient of refrigerating performance of the refrigeration plant vapour compression refrigeration system ε that does not adorn subcooler 1With coefficient of heat supply ε 2That is ε ' 1>ε 1, ε ' 2>ε 2:

Δε 1=ε′ 11=(h 3-h 4)/(h 2-h 1)……(10)

Δε 2=ε′ 21=(h 3-h 4)/(h 2-h 1)……(11)

By formula (10) and (11) as can be seen: when consuming identical work done during compression, if condensation temperature and evaporating temperature differ big more, the increment Delta h=h of refrigerating capacity then 3-h 4Big more, the increment Delta h=h of heating load 3-h 4Also big more; Thereby make the energy-saving and emission-reduction doulbe-sides' victory.

Existing in addition Teat pump boiler need have one as the off-premises station of evaporimeter and the water tank as Teat pump boiler condenser of holding concurrently, and existing air-conditioner need have a summer as evaporimeter, be used as the indoor set of condenser winter and be used as condenser a summer, winter is as the off-premises station of evaporimeter, if can grafting form compound unit, then kill two birds with one stone, both freezed, can obtain hot water again, only consume a electric power, energy-saving and emission-reduction do not have thermal pollution also to save totle drilling cost again, save an off-premises station.

Summary of the invention

Task of the present invention is that improved vapour compression refrigeration system of cluster and heating-cooling equipment thereof will be provided, the Teat pump boiler of subcooler and the air-conditioner multifunctional composite hot equipment that freezes for example is housed, to consume a part of high-grade energy: mechanical energy, electric energy or heat energy are compensation, from low-grade energy: the air source, the water source, energy draw heat in source, ground or its low temperature heat energy of solar heat water source, being transported in higher space of the required temperature of user or the object and going, is that family or the user of unit provide the washing hot water of having a bath and live the whole year with the exploitation excavation and the low-grade energy that is used, drinking water, heat supply in winter hot water, or industrial and agricultural production hot water; Can also provide refrigerating capacity for freezer, refrigerator, refrigerator or refrigerator; For the user provides wet monsoon cold mould air-conditioning or cold water type air-conditioning, or cooling-and-warming splitting formula air-conditioning, for dryer and drying shed provide heating capacity, than electric heater efficient electricity-saving; Bigger than its coefficient of heat supplys of refrigeration plant such as existing Teat pump boiler dryers; Bigger than its coefficient of refrigerating performance of existing refrigeration plant; Save conventional energy resource, GHG emissions mitigation, cooling and warming kills two birds with one stone, energy-saving and emission-reduction, both doulbe-sides' victorys; The common sparing parts save material again, reduce totle drilling cost.
