**Title: Understanding Basic Heat Exchanger Dynamics**

**Diagram Overview:**
The diagram represents a heat exchanger system involving air and refrigerant R134a. 

**System Description:**
1. **Inlet and Outlet Flows:**
   - Air enters the heat exchanger at point 1 and exits at point 2.
   - Refrigerant R134a enters at point 3 and exits at point 4.

**Given Conditions:**
- **Assumptions:**
  - Kinetic energy and potential energy are considered negligible.
  - The system is in a steady state.

- **Measurements:**
  - **Point 1 (Air Inlet):**
    - Pressure (P₁) = 1 Bar
    - Temperature (T₁) = 89.6°F
    - Volume flow rate (Av₁) = 1 m³/s
  - **Point 2 (Air Outlet):**
    - Pressure (P₂) = 0.95 Bar
    - Temperature (T₂) = 71.6°F
  - **Point 3 (Refrigerant Inlet):**
    - Pressure (P₃) = 5 Bar
    - Quality (x₃) = 0.2
  - **Point 4 (Refrigerant Outlet):**
    - Pressure (P₄) = 5 Bar
    - Temperature (T₄) = 68°F

**Objective:**
- **Determine the following:**
  1. Mass flow rate of refrigerant R134a in kg/s.
  2. Heat transfer rate between refrigerant R134a and air.

This setup provides a fundamental analysis of a heat exchanger's performance, necessary for understanding thermodynamic processes in cooling and heating systems.
