Abstract

The invention belongs to the field of refrigeration equipment product experiment devices and particularly relates to an air-cooling cold (hot) water unit experiment device with a surface-cooling coil pipe regulation function. The equipment device is respectively provided with independent surface-cooling coil pipes in air treatment units arranged at two sides of a machine to be tested, and is provided with a variable frequency circulation pump pipeline communicated with a constant temperature water tank for the surface-cooling coil pipes. Air return parts of condensers arranged at two sides of the machine to be tested are provided with a first air temperature sampler and a second air temperature sampler for measuring the air return dry-bulb temperature, the first air temperature sampler and the second air temperature sampler are respectively and electrically connected with a variable frequency water pump of the corresponding surface-cooling coil pipe through signal wires, further, the variable frequency pump of the corresponding surface-cooling coil pipe can be directly controlled through the air return dry-bulb temperature of the condensers arranged at two sides of the machine to be tested, the stable experiment effect is reached, and the additional cold and hot load investment is not needed. In the air-cooling cold (hot) water unit experiment device, the constant temperature water tank is communicated with a cooling tower system, the stable control of the temperature in the constant temperature water tank can be reached, and the additional electric heating investment is not needed, so the goal of sufficient energy saving is reached.

Description

technical field [0001] The invention belongs to the field of test devices for refrigeration equipment products, and in particular relates to a test device for air-cooled cold (hot) water units with the function of adjusting surface cooling coils. Background technique [0002] In recent years, with the change of social demand, the products of air-cooled cold (hot) water units have been developing towards large-scale. At present, the maximum single unit can reach 1600kw. In the corresponding test equipment, how to fully integrate the tested machine It is very important to balance the cooling and heating loads generated on the wind side and the water side to achieve sufficient energy saving. [0003] Under normal circumstances, a surface cooling circuit with a surface cooling coil is selected to be installed on the wind side of the tested machine, and a part of the load of the tested machine is balanced through the surface cooling coil, and the excess cold and heat on the wind ...
