The most likely cause of such low pressure in the high pressure side of the system would be insufficient refrigerant.

系统高压侧产生如此低压强的最可能原因是制冷剂不足。

Note: the reason why a flow arrow was not used was for applications such as pump isolation whereas preferred sealing direction and the high pressure side are not necessarily the same.

注意：不采用流向箭头的原因是，在某些应用场合，如泵隔离，其优先密封方向和高压面并一定相同。

Reducing the inlet temperature of cooling water and increasing its mass flow are favorable to increase refrigerant performance coefficient, and can decrease optimal pressure at high pressure side.

降低冷却水进口温度和提高其质量流量不仅有利于提高制冷性能系数，而且能降低最佳高压侧压力。

Also,their risk of side effects such as glaucoma, high blood pressure and edema, or swelling in the legs,was reduced.

In the study,patients who received lower doses of steroids by mouth spent less time in the hospital, and their risk of side effects such as glaucoma, high blood pressure and edema, or swelling in the legs, was reduced.

Arsenal thrashed Everton 6-1 on the opening day of the season but a repeat of that scoreline was never on the cards as a committed Toffees side put pressure on the ball high up the pitch, giving Arsenal no time to settle.
