Description

The Air Conditioner laboratory
Technical field:
The utility model relates to air conditioner enthalpy difference experiment test device, particularly a kind of lab setup that is used for the test of Air Conditioner enthalpy difference.
Background technology:
In order to strengthen the control and monitoring to civilian air-conditioning unit manufacturing firm product quality, the relevant quality testing department of country requires producer to be equipped with corresponding air conditioner group Performance Test System.In order to guarantee the product quality of Air Conditioner, manufacturing enterprise operated by rotary motion air conditioner laboratory is so that provide foundation for properties of product detect.
The Air Conditioner laboratory generally includes indoor set test cabinet, off-premises station test cabinet, indoor air treatment system, outdoor air disposal system and computer measurement and control system, wherein indoor air treatment system and outdoor air disposal system all include refrigeration unit, electric heater, humidifier and pressure fan respectively, and each refrigeration unit has included compressor, evaporator and condenser.When the test experiments that carries out Air Conditioner, the breadboard indoor of the indoor set of tested air conditioner and air conditioner air treatment system places in the indoor set test cabinet, and the breadboard outdoor air disposal system of the off-premises station of tested air conditioner and air conditioner places in the off-premises station test cabinet, and indoor air treatment system and outdoor air disposal system are respectively applied for the air condition of regulating in indoor set test cabinet and the off-premises station test cabinet.Test beginning back starts tested air conditioner, because tested Air Conditioner power is very big, its indoor set can produce bigger cold, and off-premises station then can discharge bigger heat.In order to reach and to keep and test desired environmental working condition, normally the refrigeration unit by indoor and outdoor side two air treatment systems is earlier with the cooling of the air in indoor set test cabinet and the off-premises station test cabinet, and then the electricity consumption heater heats, controls the dry-bulb temperature and the wet-bulb temperature of environment in two test cabinets with the humidifier humidification.
Reach and keep in the process of experimental situation operating mode at this, offset the supercooled that part of energy of refrigeration unit in the air treatment system with heating, this has just caused extra energy dissipation, has increased electrically heated energy consumption, has improved the cost of experiment.
Another noticeable phenomenon is in said process, tested indoor set in the indoor set test cabinet produces bigger cold, thereby environment temperature is low, so need that electric heater provides to add heat bigger, and the tested off-premises station in the off-premises station test cabinet discharges bigger heat, thereby the environment temperature height, so need that electric heater provides to add heat less; And therewith in pairs than be, because the indoor set chamber temperatures is low, how many colds are refrigeration unit wherein need not produce just can reach the reference mark, therefore the heat that its condenser discharged is less, and off-premises station chamber temperatures height, refrigeration unit wherein must produce big cold just can reach the reference mark, so the heat that its condenser discharged is just more.
The utility model content:
Technical problem to be solved in the utility model is to overcome the defective that existing air conditioner laboratory energy consumption is big, experimental cost is high, a kind of Air Conditioner laboratory is provided, it can make full use of used heat, the purpose of reduce energy consumption to reach, saving the energy reaching and keep in the process of experimental situation operating mode.
The technical scheme in the invention for solving the technical problem is as follows:
A kind of Air Conditioner laboratory, include indoor set test cabinet, off-premises station test cabinet, place this indoor set test cabinet the indoor air treatment system, place the outdoor air disposal system of this off-premises station test cabinet, this indoor air treatment system and outdoor air disposal system include indoor refrigeration unit and outside refrigeration unit respectively, described indoor refrigeration unit includes the indoor heat recovering heat exchanger, and described outside refrigeration unit includes the outside heat recovering heat exchanger.
The breadboard indoor of Air Conditioner described in the utility model heat recovering heat exchanger is arranged in the off-premises station test cabinet, and described outside heat recovering heat exchanger is arranged in the indoor set test cabinet.
Improve the heating part in traditional Air Conditioner laboratory in Air Conditioner described in the utility model laboratory, in indoor refrigeration unit and outside refrigeration unit, all increased heat recovering heat exchanger, utilize the useless heat that produces in the two refrigeration unit courses of work to be transmitted in the indoor unit and outdoor unit test cabinet by this heat recovering heat exchanger, thereby part so that the original electric heater of replacing whole heat the air in two test cabinets, to reach and to keep the operating mode of experimental situation.Because the used heat that the utility model has effectively utilized refrigeration unit to produce heats, therefore, the energy consumption that described Air Conditioner laboratory greatly reduces electric heater has reduced the waste of the energy, has reached the beneficial effect of saving the energy.
In addition as mentioned above, because tested Air Conditioner power is very big, therefore in the experimentation indoor set test indoor temperature low, required provide to add heat big, off-premises station test indoor temperature height, required provide to add heat little, and refrigeration unit working load heat little, that discharged in indoor is few, and refrigeration unit working load heat big, that discharged in outside is many.Thereby, the utility model is distributed the heat recovering heat exchanger of indoor refrigeration unit and outside refrigeration unit rationally, the indoor heat recovering heat exchanger is arranged in the off-premises station test cabinet, described outside heat recovering heat exchanger is arranged in the indoor set test cabinet, the heat recovering heat exchangers that are about to two refrigeration units intersect placement, make the lower indoor set test cabinet of outside heat recovering heat exchanger heating-up temperature that discharges big heat, the higher off-premises station test cabinet of indoor heat recovering heat exchanger heating-up temperature that release heat is less, thereby utilize the recovery heat of refrigeration unit more scientifically and rationally, make the breadboard waste heat recovery rate of described Air Conditioner higher, energy-saving effect is more remarkable.Therefore, the utility model is under most of operating mode, and the heat that heat recovering heat exchanger discharged can satisfy the requirement of air heat in the indoor unit and outdoor unit test cabinet and needn't use electric heater, only just needs to use the electric heater heating under indivedual operating modes.
