Embodiment Construction

[0009] Such as figure 1 The structure diagram of the air-cooled heat pump test system is shown, the tested unit environmental chamber 9 is used to place the tested unit 1, the tested unit environmental chamber 9 is equipped with an air intake and exhaust control system, and the air treatment box 10 is installed in the tested unit environmental chamber Inside 9, part of the cold water produced during the operation of the tested unit 1 enters the heat balance water tank 2, and the other part is mixed with the water from the heat balance water tank 2 and then enters the evaporator of the tested unit 1. By adjusting the mixing ratio of the two parts of water , to realize the outlet water temperature control of the tested unit 1, the condensation heat generated by the condenser of the tested unit 1 is taken away by the surface cooler 6 in the air handling box 10 placed in the tested unit’s environmental chamber 9 after heat exchange, and the surface cooling The refrigerant water fl...

Abstract

The invention relates to an air cooled heating pump test system. An air treatment box is arranged inside a tested unit environment chamber, and a heat balance water tank is arranged outside the tested unit environment chamber; and cold capacity and heat are distributed and balanced between a surface cooler in the air treatment box and the heat balance water tank through the tested unit and an external cold source or an external heat source, so that requirements on water supply in different temperature regions is met. In a test process, control of the temperature and the humidity of the whole environment system can be executed by adjusting the flow of coolant water entering the air treatment box in the test chamber without extra heat source input. The air inlet temperature of a condenser of a large-size air cooling and heating pump unit can be independently controlled in different regions; in a season that outdoor temperature is relatively low, a working condition required by test of the tested unit can be realized by only controlling the air inlet amount and the air exhaust amount getting into and getting out of the test chamber; and the test energy consumption of the unit can be saved by 50 percent. The system can be used for product development experiments and test of the performance of the tested unit of an air cooled heating pump production line.

Description

technical field [0001] The invention relates to an air-conditioning performance testing technology, in particular to an air-cooled heat pump testing system. Background technique [0002] Air-cooled heat pumps are currently the most widely used air-handling equipment in the refrigeration and air-conditioning industry, which can achieve the purpose of cooling in summer and heating in winter. The manufacturing plant must be equipped with a test system capable of comprehensively inspecting the equipment performance of the unit to ensure that the equipment leaving the factory meets the requirements of national standards or even international standards. In recent years, the production of large-scale air-cooled heat pumps in China has increased rapidly, and the requirements for their performance testing systems are also getting higher and higher. The traditional air-cooled heat pump performance test system uses an external cold source for cooling to balance the condensation heat o...
