Seven, (Full marks 12 points) A 
home appliance manufacturing company, based on market research and analysis, has decided to adjust its production plan. They plan to produce a total of 360 units of air conditioners, color TVs, and refrigerators per week (calculated at 120 labor hours per week), with at least 60 refrigerators to be produced. The labor hours required per unit and the output value per unit of these home appliances are as follows:

How many units of air conditioners, color TVs, and refrigerators should be produced each week to maximize output value? What is the highest output value (in thousand yuan)?

\because x+y+z=360 \text {, then } z \geqslant 60 \text {, } \\
\therefore x+y \leqslant 300 \text {. } \\
\text { Total labor hours }=\frac{1}{2} x+\frac{1}{3} y+\frac{1}{4} z \\
=\frac{1}{12}(6 x+4 y+3 z) \\
=\frac{1}{4}(x+y+z)+\frac{1}{12}(3 x+y) \\
=\frac{1}{4} \times 360+\frac{1}{12}(3 x+y) \\
=90+\frac{1}{12}(3 x+y) \text {. } \\
\text { Total output value }=4 x+3 y+2 z \\
=2(x+y+z)+(2 x+y) \\
=2 \times 360+(2 x+y) \\
=720+(2 x+y) \text {. } \\
\left\{\begin{array}{l}
x+y \leqslant 300, \\
90+\frac{1}{12}(3 x+y)=120 \Rightarrow 3 x+y=360
\end{array}\right\} \Rightarrow\left\{\begin{array}{l}
x \geqslant 30, \\
3 x+y=360
\end{array}\right\} \\
\Rightarrow A=1080-x \leqslant 1050 \text {, } \\
\end{array}
$$

When the total output value $A$ reaches its maximum value of 1050, $x=30, y=270$, $z=60$.

Answer: Each week, 30 air conditioners, 270 televisions, and 60 refrigerators should be produced to maximize the output value. The maximum output value is 1050 thousand yuan.
