Summary of the invention
The test macro that the purpose of this invention is to provide the cold and hot amount of a kind of water source heat pump units; Utilize in the water source heat pump units operational process to be tested the waste heat recovery of self to come the cooling load of balance water source heat pump units to be tested, need not adopt outside cold and heat source just can reach required refrigeration of tested test-run a machine or thermal condition requirement.
Technical scheme of the present invention is following:
The test macro of the cold and hot amount of a kind of water source heat pump units; Include cooling tower, hot hopper, cold hopper; Said cold hopper, hot hopper are connected with the outlet of unit condenser to be tested respectively, and hot hopper is connected with the import of unit condenser to be tested; Cold hopper, hot hopper are connected with the outlet of unit evaporator to be tested respectively, and cold hopper is connected with the import of unit evaporator to be tested; Be provided with water circulating pump in the connecting tube between the import of cold hopper and unit evaporator to be tested, be provided with water circulating pump in the connecting tube between the import of hot hopper and unit condenser to be tested.
Be provided with flowmeter in the connecting tube between the outlet of described cold hopper, hot hopper and unit condenser to be tested, cold hopper, hot hopper are provided with flowmeter respectively and in the connecting tube between the outlet of unit evaporator to be tested.
Be parallel with by-pass valve in the described water circulating pump.
The present invention compares with prior art that can to produce following good effect following:
Because no outside Cooling and Heat Source (test machine) has reduced the equipment investment at initial stage, system does not have other energy consumption equipments and electrical heating again except that water circulating pump, cooling tower, and operating cost is low.Also avoided simultaneously the waste gas that running produced, the used heat contaminated environment of tested test-run a machine and test machine, it also is an a kind of energy-saving and noise-reducing system, has certain social economic benefit value.
