Country Surroundings: Some Nuggets of Fact Swiss weather and temperatures are governed by so many special features of geography and meteorology that some parts of the country may prove attractive to the visitor during any and every month. Within the borders of this land, substantially smaller than New Hampshire and Vermont together, there is a "world of weather." If it doesn't suit you where you are you may at least try your luck in some other canton or at some other altitude, effecting a drastic change in your surroundings within two or three hours.
Because there was only one large nursery in our area (specializing in trees for road works) when we moved in 16 years ago, and all our available funds had to go into renovating our old farmhouse, work in the garden meant transplanting wild ferns and flowers from the woods or fields and selectively cutting some of the available trees. Since many of these plants have a natural beauty and fit perfectly within our country surroundings, much of our landscaping continues to deal with wild plants.
A heat Pump system consists essentially of a motor-driven compressor, a condenser, an expansion valve, and an evaporator. Liquid, piped to a lake, stream, earth, or other heat source, flows through an expansion valve, which lowers its pressure and temperature. It then enters the evaporator, where it evaporates, absorbing heat from the surroundings. The gas is pumped from the evaporator to the condenser by the compressor. The compressor does work on the gas in compressing it, and this work raises its temperature and pressure. In the condenser the gas gives off a great amount of heat to its surroundings as it becomes a liquid. The cycle is then repeated. |
