Description

Technical Field

[0001] The utility model relates to room air-conditioning performance test experimental air supply equipment, belonging to the technical field of five-constant cold and heat source equipment performance test laboratory. Background Art

[0002] The common air enthalpy difference method or water calorimeter method is used to measure the cooling capacity, heating capacity, low-temperature non-steady-state heating capacity, power consumption, circulating air volume, and seasonal energy consumption efficiency of room air conditioners, etc., which can be used as an important means of testing equipment and design and development of room air conditioners. The cold and hot enthalpy difference laboratory can simulate high-temperature and low-temperature climate environments to verify the cooling and heating capacity of the cold and hot source host in harsh climate environments, detect whether the system has reached the set cooling and heating capacity, and whether the cooling water temperature and heating water temperature can meet the design requirements; detect the inlet and outlet water temperatures of the medium-temperature cold water in the cold and hot source equipment, and verify the stability of the water temperature. The air supply equipment of the room air conditioning performance test experiment generally uses a hot air blower to deliver hot air, and a cold air blower to deliver cold air. The low-temperature cold air generated by the cold air blower enters the hot and cold enthalpy difference laboratory through the channel formed by the cold air outlet pipe and the air supply pipe. When the low-temperature cold air flows through the cold air outlet pipe, the cold air outlet will be in a low-temperature state. Therefore, the water vapor in the air is easy to condense on the cold air outlet pipe. With the accumulation of condensed water on the cold air outlet pipe, condensed water will drip randomly in the environment where the cold air blower is located, causing the environment where the cold air blower is located to be dirty and messy.
