How to create the heat transfer between MA and MA and how to know the temperature and humidity of the outlet air in the cooling tower?

I am creating a MA heat recovery system in simscape (mainly to consider the recovery of condensate water) and need a heat exchanger for moist air to moist air. In addition, how to know the temperature and humidity of the cooling tower outlet?

Creating a heat recovery system for moist air (MA) in Simscape involves a few essential steps. Begin by opening Simulink and navigating to the Moist Air section in the Library Browser. Add key components such as Volumetric Flow Rate Source (MA), Reservoir (MA), Moist Air Properties (MA), and Heat Exchanger (MA).
Configure the Heat Exchanger (MA) by connecting the Volumetric Flow Rate Source (MA) to its inlet and linking its outlet to the Reservoir (MA). Set the necessary parameters for the heat exchanger, including heat transfer coefficients and surface area. To monitor the system, add Pressure & Temperature Sensor (MA) and Humidity & Trace Gas Sensor (MA) at various points to measure temperature and humidity.
To determine the cooling tower outlet conditions, model the cooling tower by adding a Heat Exchanger (MA), Volumetric Flow Rate Source (MA), and Reservoir (MA). Place the sensors at the cooling tower outlet to measure temperature and humidity. Connect and configure these sensors, then set up and run the simulation to log the data and analyze the system's performance.
To know more, refer to the documentaion pages of all these blocks from Moist Air Models - MATLAB & Simulink (mathworks.com).
You can also refer to this article in order to get started on modeling moist air systems at Modeling Moist Air Systems - MATLAB & Simulink (mathworks.com) and relevant examples at Moist Air Systems — Examples (mathworks.com) and Moist Air Models — Examples (mathworks.com).
Hope this helps!

A cooling tower module is available in simscape, but the outlet temperature of the air is not given, and there is no air-to-air heat exchanger module

Can you try this block : Heat exchanger for systems with two gas flows - MATLAB (mathworks.com) for air-to-air heat exchanger module?
Also, can you not use Pressure & Temperature Sensor (MA) and Humidity & Trace Gas Sensor (MA) at the outlet of the cooling tower to measure the required parameters over A2 and B2 ports of the cooling tower module?
