Air cooled heating pump test system

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...
