Abstract
Abstract A device for controlling the temperature and the humidity of the air in a barn has a thermostat, humidistat, heater and damper to maintain the desired proper temperature and humidity conditions for animal housing. The temperature is held at a desired level by the thermostat which monitors the temperature and heats and circulates the existing air in the barn as required. In addition, the humidistat initiates a process of heating outside air and supplying of heated dry air to the barn in response to abnormally high humidity conditions and thereby maintains the desired optimum temperature and humidity conditions.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
181 words
A climate control to regulate the temperature and humidity of the air in a barn comprising: (a) temperature sensing means for detecting the temperature of the air in said barn and for comparing it to a preselected temperature; (b) relative humidity sensing means connected with said temperature sensing means for detecting the relative humidity of the air in said barn and for comparing it to a preselected relative humidity; (c) air circulating means operable by at least one of said temperature sensing means and said relative humidity sensing means for circulating the air in said barn; (d) heating means operable by at least one of said temperature sensing means and said relative humidity sensing means for heating the air circulated by said circulating means; (e) ventilating means operable by said relative humidity sensing means and connected to said heating means for introducing outside hot air into said barn; (f) and a minimum temperature sensing means for detecting the entrance of cold air into said barn and for discontinuing the operation of said air circulating means upon detection of said cold air.
Claim 2
Dependent Claim
181 words
A climate control to regulate the temperature and humidity of the air in a barn comprising: (a) temperature sensing means for detecting the temperature of the air in said barn and for comparing it to a preselected temperature; (b) relative humidity sensing means connected with said temperature sensing means for detecting the relative humidity of the air in said barn and for comparing it to a preselected relative humidity; (c) air circulating means operable by at least one of said temperature sensing means and said relative humidity sensing means for circulating the air in said barn; (d) heating means operable by at least one of said temperature sensing means and said relative humidity sensing means for heating the air circulated by said circulating means; (e) ventilating means operable by said relative humidity sensing means and connected to said heating means for introducing outside hot air into said barn; (f) and a minimum temperature sensing means for detecting the entrance of cold air into said barn and for discontinuing the operation of said air circulating means upon detection of said cold air.
Claim 3
Dependent Claim
180 words
A climate control to regulate the temperature and humidity of the air in a barn comprising: (a) temperature sensing means for detecting the temperature of the air in said barn and for comparing it to a preselected temperature; (b) relative humidity sensing means connected with said temperature sensing means for detecting the relative humidity of the air in said barn and for comparing it to a preselected relative humidity; (c) air circulating means operable by at least one of said temperature sensing means and said relative humidity sensing means for circulating the air in said barn; (d) heating means operable by at least one of said temperature sensing means and said relative humidity sensing means for heating the air circulated by said circulating means; (e) ventilating means operable by said relative humidity sensing means and connected to said heating means for introducing outside hot air into said barn; (f) and an air flow sensing means for detecting the restriction of air flow through said heating means and for discontinuing the operation of said heating means upon detection of said restriction.
Claim 4
Dependent Claim
